ALKALI METALS - RED Li, Na, K, Rb, Cs, Fr Valence electron – 1 very reactive metals that do not occur freely in nature malleable, ductile, good conductors of heat and electricity. softer than most other metals can explode if they are exposed to water

ALKLINE EARTH METALS - orange Be, Mg, Ca, Sr, Ba, R Valence electron – 2 metals very reactive not found free in nature

TRANSITION METALS - white 21-30, 39-48, 72-80, 104-112 Valence electron – 1 or 2 Ductile and malleable, and conduct electricity and heat Iron (Fe), cobalt (Co), and nickel (Ni), are the only elements known to produce a magnetic field.

Boron Family - brown B, Al, Ga, In, Tl Valence electron – 3 Metal and metalloids Used as cleaning, water softner

Carbon Family - grey C, Si, Ge, Sn, Pb Valence electrons – 4 Non metals, metalloids, and metals Bond with many elements Used in transistors

Nitrogen Family - pink N, P, As, Sb, Bi Valence electrons – 5 Non metals, metalloids, and metals

Oxygen Family - green _________________________________ Valence electrons – _________ _____________, _____________, and _____________ Very _________________
