All forms of matter
Try to stay at their lowest possible energy state, called the ground state
Valence electrons are
Electrons farthest away from the nucleus. In general the electrons with the highest energy level number
Atoms in the same column of the periodic chart have
The same number of valence electrons and thus a similar chemistry
Octet rule states that
Atoms strive to attain 8 valence electrons
Ionization is
The process by which an atom turns into an ion by gaining or losing electrons
Covalent bond is
a shared pair of valence electrons that holds atoms together in covalent compounds
