Comments

For chemical elements there are single-, double- and triple-bond covalent radii. This sequence lists single-bond covalent radii.

The values for chemical elements in each period (1 - 2, 3 - 10, 11 - 18, 19 - 36, 37 - 54, 55 - 86) are overall decreasing, but the trend is not so obvious as in A319904.

Example

The single-bond covalent radii for hydrogen (1), helium (2) and lithium (3), etc. are 32 pm, 46 pm, 133 pm, etc.
