Metals, Metalloids, and Nonmetals - Angelo State University

The nonmetals gain electrons until they have the same nuer of electrons as the nearest noble gas (Group 8A), forming negatively charged anions which have charges that are the group nuer minus eight. That is, the Group 7A nonmetals form 1- charges, the Group 6A nonmetals form 2- charges, and the Group 5A metals form 3- charges.
