Clearly, the hydrogen atom has the one valence electron.


The hydrogen atom has only the one electron, and clearly this is the valence electron. The hydrogen atom can thus be either oxidized to give what, or reduced to give the hydride anion, #H^-#.

Clearly the valence electrons of 2 hydrogen atoms can couple to give a covalent bond, and which molecule?

#2H* rarr H-H#
