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

What group are the Lanthanide/Actinide in? transition metals

Lanthanide Characteristics 1-3 valence electrons, reactive, shiny, metals

Actinide Characteristics radioactive, unstable, made in labs, 1-3 valence electrons, reactive

Boron Group Characteristics 3 valence electrons, reactive, solid at room temp

Carbon Group Characteristics 4 valence electrons, reactivity varies, solid at room temp

Nitrogen Group Characteristics 5 valence electrons, reactivity varies, solid at room temp except for nitrogen

Oxygen Group Characteristics 6 valence electrons, reactive, solid at room temp except for oxygen

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

Noble gases (Group 18) Characteristics 2 or 8 valence electrons, non-reactive, colorless, tasteless, odorless
