Families on the Periodic TableElements on the periodic table can be
grouped into families bases on their chemical properties.
Each family has a specific name to differentiate it from the other families in the periodic table.
Elements in each family react differently with other elements.

TRANSITION METALSMetalsAlmost all are
solids at room temp (Hg)
Good conductors of heat and electricity.
1 or 2 Valence Electrons
Less Reactive than Alkali and Alkaline Earth
Can bond with many elements in a variety of shapes.
