The nonmetals in groups 5a, 6a, and -form positively charged ions. -form ions with a numerical charge equal to their group number. -lose electrons when they form ions. -form ions with charges of 3–, 2–, and 1–, respectively.(it's d)

The nonmetals in Groups 5A, 6A, and 7A - form ions with charges of 3⁻, 2⁻, and 1⁻, respectively.

A nonmetal is a chemical element that usually gains electrons when reacting with metal and forms anions, acid oxides, hydrogen compounds, and acids.

Thus, The nonmetals in Groups 5A, 6A, and 7A - form ions with charges of 3⁻, 2⁻, and 1⁻, respectively.

The nonmetals in Groups 15, 16, and 17 form ions with charges of 3-, 2-, and 1-, respectively.

Explanation:

The elements of Group 18 (the noble gases) have a complete valence shell of eight electrons.

It is easier for the elements of Groups 15 to 17 to gain three, two, or one electron(s) to get a complete valence shell than it is to lose five, six, or seven valence electrons.

Thus, they form negative ions with charges of 3-, 2-, and 1-, respectively.

The charges do not correspond to the Group numbers of 15 to 17 or the old (pre-1990) Group numbers of 5A to 7A.
