Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool
How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many neutrons, which upsets the strong nuclear forces holding the atom together. Unstable nuclei try to balance themselves by giving off the excess proton or neutron either through alpha, beta minus or beta plus decay.

During radioactive decay, an unstable nucleus (the "parent") spontaneously changes to become a different nucleus (the "daughter"), emitting radiation in the process. The nuclear radiation emitted during radioactive decay is high energy, ionizing radiation. Nuclear radiation is potentially dangerous to living things but also has many beneficial applications. Types of radioactive decay include alpha, beta, and gamma.

What is Radioactivity and Is It Always Harmful: Explained in Really Simple Words
Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or radioactive radiation always harmful? Let’s discuss this in more detail.
Inside an atom’s nucleus, there are positively charged protons and neutral neutrons. These nucleons are held together by a “glue” called the strong nuclear force. This strong force cancels out the repulsive electrostatic force of like charged protons and keeps the nucleus stable. The nuclear force has a short range of action and is dependent on the ratio of neutrons and protons present in a nucleus. However, we see that the balance between the forces starts to waver in a nucleus where t...

Why Does Everything Decay Into Lead
If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is lead so special?

How Radioactive Decay Works? Explained With Animation
Radioactive decay is a natural and random process by which the nucleus of an unstable atom transforms into a more stable configuration. Radioactive decay was a puzzle for classical physics because it seemingly violated the principle of conserving energy. Quantum mechanics, however, introduces the element of randomness, allowing slightly unstable atomic nuclei to spontaneously transform into something more stable.
Even for the most unstable nuclei, predicting when a single atom will decay is impossible. This unpredictability is due to the strong nuclear force that holds protons and neutrons within the nucleus. While an atom might prefer a different combination of protons and neutrons, reaching that state requires removing or altering some components, which costs energy.
Each radioactive m...

Radioactivity: Expect the unexpected - Steve Weatherall
View full lesson: http://ed.ted.com/lessons/radioactivity-expect-the-unexpected-steve-weatherall
Neutrons don't change into protons. Except, sometimes, they do. Radioactivity is the process under which the nucleus can change spontaneously from one element to another. Steve Weatherall suggests that we acknowledge both the usefulness and danger inherent in harvesting radioactivity.

Radioactivity is the property through which a heavier, unstable nucleus assumes a more stable state by emitting radiation. The process through which a nucleus turns into a stable one is called radioactive decay. But is radioactivity or radioactive radiation always harmful? Let’s discuss this in more detail.
Inside an atom’s nucleus, there are positively charged protons and neutral neutrons. These nucleons are held together by a “glue” called the strong nuclear force. This strong force cancels out the repulsive electrostatic force of like charged protons and keeps the nucleus stable. The nuclear force has a short range of action and is dependent on the ratio of neutrons and protons present in a nucleus. However, we see that the balance between the forces starts to waver in a nucleus where the number of neutrons exceeds the number of protons. A nucleus that exceeds the threshold number of neutrons and protons that the strong nuclear force can hold together comfortably will be more unstable.
More specifically, these scenarios give rise to unstable isotopes of elements. Just as your body, through a series of expansions and contractions, expels a substance with a sneeze, similarly, the unstable isotopes of elements fling out different particles or forms of energy to restore balance between the forces in their nucleus. During this process of attaining stability, they change into a new nucleus. It is exactly this property, namely turning into something new to attain stability, that we call radioactivity.

If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is lead so special?

How Radioactive Decay Works? Explained With Animation

Radioactive decay is a natural and random process by which the nucleus of an unstable atom transforms into a more stable configuration. Radioactive decay was a puzzle for classical physics because it seemingly violated the principle of conserving energy. Quantum mechanics, however, introduces the element of randomness, allowing slightly unstable atomic nuclei to spontaneously transform into something more stable.
Even for the most unstable nuclei, predicting when a single atom will decay is impossible. This unpredictability is due to the strong nuclear force that holds protons and neutrons within the nucleus. While an atom might prefer a different combination of protons and neutrons, reaching that state requires removing or altering some components, which costs energy.
Each radioactive material has a characteristic half-life, which is the time it takes for half of a sample of that material to undergo radioactive decay. Different radionuclides have different half-lives, ranging from fractions of a second to millions of years. While we can't predict precisely when a particular nucleus will decay, we can estimate how long it will take for a given quantity of radioactive material to decay. This predictability is based on statistical principles and many atoms involved.
Despite this unpredictability at the atomic level, we can make statistical predictions for populations of atoms. This concept underlies the notion of a half-life, which specifies the time it takes for half the mass of a radioactive substance to undergo decay.

Neutrons don't change into protons. Except, sometimes, they do. Radioactivity is the process under which the nucleus can change spontaneously from one element to another. Steve Weatherall suggests that we acknowledge both the usefulness and danger inherent in harvesting radioactivity.
