Hydrogen has only one valence electrons.
The outer shell (N=4) of the copper element has 2 electrons.
Berkelium has 97 electrons, which means it has 7 electron shells.
They have 8 electrons on the outermost shell, also known as valence.
Two electrons will fill a hydrogen's outer, or valence, shell.
More the number of shells in an atom, more away will be the electrons from the nucleus. Hence, weaker will be the attraction between nucleus and outermost electrons. So atom with more shells will let go their electrons easier than atoms with fewer shells.
Beryllium has one outer electron shell with two electrons.
Atoms can have a maximum of 8 electrons in their outermost energy level, except hydrogen and helium which can have a maximum of 2 electrons. The number of electrons in the outer shell determines an atom's chemical properties and reactivity.
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.
