Well, there is ONE valence electron in atomic hydrogen....

Explanation:

...why? For hydrogen, #Z=1#; there is ONE positively-charged, nuclear particle. For neutrality, there must be ONE negatively-charged EXTRANUCLEAR particle, and we call these beasts electrons.

Undr standard conditions, the electrons overlap to for form an #H-H# bond, to give the dihydrogen molecule, #H_2#...
