Atomic number

In chemistry and physics, the atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons.

The atomic number, Z, should not be confused with the mass number, A, which is the number of nucleons, the total number of protons and neutrons in the nucleus of an atom. The number of neutrons, N, is known as the neutron number of the atom; thus, A = Z + N (these quantities are always whole numbers). Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity called the "relative isotopic mass"), is roughly (to within 1%) equal to the whole number A.

Nitrogen

Nitrogen is a chemical element with symbol N and atomic number 7. It is the lightest pnictogen and at room temperature, it is a transparent, odorless diatomic gas. Nitrogen is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System. On Earth, the element forms about 78% of Earth's atmosphere and as such is the most abundant uncombined element. The element nitrogen was discovered as a separable component of air, by Scottish physician Daniel Rutherford, in 1772.

Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen. The extremely strong triple bond in elemental nitrogen (N≡N) dominates nitrogen chemistry, causing difficulty for both organisms and industry in converting the N₂ into useful compounds, but at the same time causing release of large amounts of often useful energy when the compounds burn, explode, or decay back into nitrogen gas. Synthetically produced ammonia and nitrates are key industrial fertilizers and fertilizer nitrates are key pollutants in causing the eutrophication of water systems.

Oxygen

Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms compounds (notably oxides) with most elements. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O
2. Diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. However, monitoring of atmospheric oxygen levels show a global downward trend, because of fossil-fuel burning. Oxygen is the most abundant element by mass in the Earth's crust as part of oxide compounds such as silicon dioxide, making up almost half of the crust's mass.

Many major classes of organic molecules in living organisms, such as proteins, nucleic acids, carbohydrates, and fats, contain oxygen, as do the major inorganic compounds that are constituents of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as it is a part of water, the major constituent of lifeforms. Oxygen is used in cellular respiration and released by photosynthesis, which uses the energy of sunlight to produce oxygen from water. It is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Another form (allotrope) of oxygen, ozone (O
3), strongly absorbs UVB radiation and consequently the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation, but is a pollutant near the surface where it is a by-product of smog. At even higher low earth orbit altitudes, sufficient atomic oxygen is present to cause erosion for spacecraft.

  Atomic Number & Mass Number | Properties of Matter | Chemistry | FuseSchool How do we tell elements apart from each other? Find out in this video from the Properties of Matter chapter of FuseSchool GCSE Chemistry. When you look at the periodic table you will see that each element has its own box, and within that box, you will find two numbers. The atomic number, or proton number, and the mass number, but what do these numbers mean? The atomic number has the symbol 'z', this number tells you how many protons are in one atom of an element. The number is always the same for all atoms of a particular element. Atoms of different elements have different atomic numbers, meaning they have different numbers of protons. For example, an atom of Hydrogen has an atomic number of 1 because it has ...

Workbooks for schools from 50p per copy. Visit freesciencelessons.co.uk/school-licences This video is based on the AQA spec. If you are following a different exam board then you should check your specification. In this video, we look at the atomic number and mass number. First, I discuss how to use the atomic number and the mass number to work out the numbers of protons, neutrons and electrons in atoms of specific elements. We then look at what is meant by isotopes and why these differ in the mass number. Finally, we learn how to work out the structure of ions.

Atomic Number & Mass Number | Properties of Matter | Chemistry | FuseSchool How do we tell elements apart from each other? Find out in this video from the Properties of Matter chapter of FuseSchool GCSE Chemistry. When you look at the periodic table you will see that each element has its own box, and within that box, you will find two numbers. The atomic number, or proton number, and the mass number, but what do these numbers mean? The atomic number has the symbol 'z', this number tells you how many protons are in one atom of an element. The number is always the same for all atoms of a particular element. Atoms of different elements have different atomic numbers, meaning they have different numbers of protons. For example, an atom of Hydrogen has an atomic number of 1 because it has 1 proton, but an atom of Oxygen has and atomic number of 8 because it has 8 protons. The next number we look at is the mass number. The mass number has the symbol A. The mass number tells you how many protons and neutrons are in one atom of an element. We need to remember that Protons and Neutrons each have a relative mass of 1 and that Electrons are so small, that their mass does not need to be considered in the mass number of an atom. So if we know the mass number of an element, and we know the atomic number, we can calculate the number of Neutrons in an atom of a particular element. So the Mass Number = The Atomic Number + the Number of Neutrons. The Atomic Number is just the number of Protons and Atoms, therefore, the Mass Number = protons + neutrons. So if we take oxygen: oxygen has a mass number of 16 and 8 Protons, how many neutrons does it have? Remember, Mass Number = protons + neutrons We can rearrange this to show that Neutrons = Mass Number - Atomic Number. Neutrons = 16 - 8 = 8 Oxygen therefore has 8 neutrons. Let take another example. Lithium has a mass number of 7 and an atomic mass of 3, how many neutrons does it have? Mass Number = protons + neutrons; we can rearrange this to show that Neutrons = Mass Number - Atomic Number. Neutrons = 7 - 3, = 4 Lithium therefore has 4 neutrons. So the atomic number is the number of protons in an atom and the mass number is the number of protons and neutrons in an atom.

Workbooks for schools from 50p per copy. Visit freesciencelessons.co.uk/school-licences This video is based on the AQA spec. If you are following a different exam board then you should check your specification. In this video, we look at the atomic number and mass number. First, I discuss how to use the atomic number and the mass number to work out the numbers of protons, neutrons and electrons in atoms of specific elements. We then look at what is meant by isotopes and why these differ in the mass number. Finally, we learn how to work out the structure of ions.

Atomic Number & Mass Number | Properties of Matter | Chemistry | FuseSchool How do we tell elements apart from each other? Find out in this video from the Properties of Matter chapter of FuseSchool GCSE Chemistry. When you look at the periodic table you will see that each element has its own box, and within that box, you will find two numbers. The atomic number, or proton number, and the mass number, but what do these numbers mean? The atomic number has the symbol 'z', this number tells you how many protons are in one atom of an element. The number is always the same for all atoms of a particular element. Atoms of different elements have different atomic numbers, meaning they have different numbers of protons. For example, an atom of Hydrogen has an atomic number of 1 because it has 1 proton, but an atom of Oxygen has and atomic number of 8 because it has 8 protons. The next number we look at is the mass number. The mass number has the symbol A. The mass number tells you how many protons and neutrons are in one atom of an element. We need to remember that Protons and Neutrons each have a relative mass of 1 and that Electrons are so small, that their mass does not need to be considered in the mass number of an atom. So if we know the mass number of an element, and we know the atomic number, we can calculate the number of Neutrons in an atom of a particular element. So the Mass Number = The Atomic Number + the Number of Neutrons. The Atomic Number is just the number of Protons and Atoms, therefore, the Mass Number = protons + neutrons. So if we take oxygen: oxygen has a mass number of 16 and 8 Protons, how many neutrons does it have? Remember, Mass Number = protons + neutrons We can rearrange this to show that Neutrons = Mass Number - Atomic Number. Neutrons = 16 - 8 = 8 Oxygen therefore has 8 neutrons. Let take another example. Lithium has a mass number of 7 and an atomic mass of 3, how many neutrons does it have? Mass Number = protons + neutrons; we can rearrange this to show that Neutrons = Mass Number - Atomic Number. Neutrons = 7 - 3, = 4 Lithium therefore has 4 neutrons. So the atomic number is the number of protons in an atom and the mass number is the number of protons and neutrons in an atom.

Atomic number

In chemistry and physics, the atomic number of a chemical element (also known as its proton number) is the number of protons found in the nucleus of an atom of that element, and therefore identical to the charge number of the nucleus. It is conventionally represented by the symbol Z. The atomic number uniquely identifies a chemical element. In an uncharged atom, the atomic number is also equal to the number of electrons.

The atomic number, Z, should not be confused with the mass number, A, which is the number of nucleons, the total number of protons and neutrons in the nucleus of an atom. The number of neutrons, N, is known as the neutron number of the atom; thus, A = Z + N (these quantities are always whole numbers). Since protons and neutrons have approximately the same mass (and the mass of the electrons is negligible for many purposes) and the mass defect of nucleon binding is always small compared to the nucleon mass, the atomic mass of any atom, when expressed in unified atomic mass units (making a quantity called the "relative isotopic mass"), is roughly (to within 1%) equal to the whole number A.
