Valence Electrons• The number of electrons in the atom’s outer
shell. This affects how reactive an atom is.
This is indicated for each column/group by the number in front of the letter above
Valence ElectronsColumn/Group
1A has 1 valence electron
Column/Group 8A has 8 valence electron
(except for He which has 2)

living organisms

Diatomic Molecules Molecules that naturally appear in pairs such a
O2
These are still elements, NOT compounds
