PERIODS:they are the lines going side to side they show the number of energy levels
GROUPS:are the vertical rows in the table the show the number of valance electrons

- In chemistry, a valence electron is an electron that is associated with an atom, and that can participate in the formation of a chemical bond; in a single covalent bond, both atoms in the bond contribute one valence electron
- METALS
The alkali metals, found in group 1 of the periodic table, are highly reactive metals
The alkaline earth elements are metallic elements found in the second group of the periodic table
The 38 elements in groups 3 through 12 of the periodic table are called "transition metals."
The "other metals" elements are located in groups 13, 14, and 15.
Non-metals are the elements in groups 14-16 of the periodic table.
Metalloids
Metalloids are the elements found between the boundary that distinguishes metals from non-metals.

ATOMIC NUMBER he atomic number is the number located in the upper left corner shows # of protons
ATOMIC MASS atomic weight is the number located on the bottom and shows us the number of the protons plus the neutrons
stabilization: the more valence electrons they have the less likely they are sable
metals are malleable
