Answer:
In group 1, all elements except for hydrogen are alkaline metals. The Earth metals make up group 2. Every element in group 3 are transition metals. In group 17 are all nonmetals called halogens.
Explanation:
Group 1's oxides are soluble in water. Group 2's oxides and hydroxides are alkaline in nature. Group 3's three valence electrons are in their highest energy orbitals. Finally, group 17's 7 valence electrons need to gain one more to complete their octet.
