Noble Gases

This group has 1 valence electron. Therefore, it is the most reactive of all the groups.

Group 1: Alkali Metals

This group has 2 valence electrons.

Group 2: Alkaline Earth Metals

This group must be worked out to figure out the number of valence electrons. This group is made up of metals.

Group 3-12: Transition Metals

This group has 3 valence electrons.

Group 13: Boron Family

This group has 4 valence electrons.

Group 14: Carbon Family

This group has 5 valence electrons.

Group 15: Nitrogen Family

This group has 6 valence electrons.

Group 16: Oxygen Family

This group has 7 valence electrons.

Group 17: Halogens

This group has 8 valence electrons. Therefore, it is the most nonreactive. This group is stable. This group is also composed of gases.
