Color the groups
Columns The vertical (up and down) columns of the periodic table (there are 18) are called groups or families. Elements in the same group or family have similar characteristics or properties.
Rows The horizontal rows of the periodic table are called periods. Elements in a period are not alike in properties. The first element in a period is usually an active solid, and the last element in a period is always an inactive gas.
Rows Atomic mass (number of protons) increases from left to right across a period.
Rows Electrons are added one at a time moving from left to right across a period
