Question

Which groups of the periodic table want to gain electrons? What kind(s) of elements are these groups

Answer 1

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Explanation:

Answer 2

The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.

The periodic table is composed of 18 groups and 8 periods of elements. Groups 1 - 13 are metals while groups 15 -18 are nonmetals. Group 14 consists of a mixture of metals and nonmetals.

The nonmetals usually accept electrons while metals electrons easily donate electrons. Elements of group 18 neither receive nor donate electrons because they have a complete octet.

Nonmetals of groups 15 -17 gain electrons easily.
