Question

when looking across the periodic table from left to right, which of these groups are the first to contain nonmetals? group 2 group 7 group 14 group 18

Explanation:

Group 14 elements include carbon (a non - metal), silicon (a metalloid), germanium (a metalloid), tin (a metal), and lead (a metal). As we move from left to right across the periodic table, group 14 is the first group that contains a non - metal (carbon). Group 2 contains only metals (alkaline earth metals). Group 7 contains halogens (all non - metals but it is further to the right than group 14). Group 18 contains noble gases (all non - metals but it is the last group on the right).

Answer:

group 14
