Hydrogen has only one valence electrons.
The outer shell (N=4) of the copper element has 2 electrons.
Berkelium has two electrons on the outer shell.
They have 8 electrons on the outermost shell, also known as valence.
Two electrons will fill a hydrogen's outer, or valence, shell.

Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
