Please make a donation to keep the OEIS running. We are now in our 55th year. In the past year we added 12000 new sequences and reached 8000 citations (which often say "discovered thanks to the OEIS"). We need to raise money to hire someone to manage submissions, which would reduce the load on our editors and speed up editing.

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.
