#16 InChI's with hydrogen for single atoms

[pmatos]

Hi,

We are developing the ChEBI database and need to model atoms.
When we generate an InChI for a Lithium atom from the following molfile we get InChI=1/Li.H. It adds an extra hydrogen?

However when we generate an InChI for Cobalt by replacing Li with Co in the above file we get InChI=1/Co. There is no hydrogen generated.

Can you explain the discrepancy.

Cheers,
