COMMENTS

For chemical elements there are empirically measured atomic radii, calculated atomic radii, van der Waals radii and covalent radii to measure the "size" of their atoms. This sequence lists the calculated atomic radii.

The values for chemical elements in each period (1 - 2, 3 - 10, 11 - 18, 19 - 36, 37 - 54, 55 - 86) are decreasing except for those of some lanthanide elements.

EXAMPLE

The calculated atomic radii for hydrogen (1), helium (2) and lithium (3), etc. are 53 pm, 32 pm, 167 pm, etc.
