Equals the protons and increases by one through the periodic table
Atomic number
Alkali metals
Column 1, react with water
Alkali earth metals
Column 2, react less than alkali metals
Noble gases
Column 8, don’t react
Most elements are

Describe electrons
Outside nucleus, no mass, charge 1-
Describe protons
In nucleus, mass 1, charge 1+
Describe neutrons
In nucleus, mass 1, no charge
Valence electrons
Outside electrons
Isotope
An atom with a different # of neutrons, giving it a different mass
Ion
An atom with a different # of electrons giving it a charge
Protons + neutrons =
Atomic mass
Protons - Electrons =
Change
