1. HYDROCARBONS? 2. ALKANES?

i'm not exactly AMAZING at this but i did some research and this is what i think it is i'm also not in this grade but i tried.

b.final

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
