Alkali metals (Group 1) characteristics
soft, most reactive metals, easily give away valence electrons, 1 valence electron
Alkaline-earth metals (Group 2) characteristics
2 valence electrons, burn brightly, soft, silvery white, high melting point/density
Transition metals (Groups 3-12)
good thermal conductors, shiny, electric conductors, higher density and melting points than group 1+2, 1-2 valence electrons
Nitrogen Group Characteristics
5 valence electrons, reactivity varies, solid at room temp except for nitrogen
Halogens (Group 17) Characteristics
7 valence electrons, very reactive, causes violent reactions with reacting with other elements, at least one element from each state of matter
