The nonmetals in Groups 5A, 6A, and 7A...
-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)

Answer 1

Answer:

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.

Answer 2

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.

• Non-metals are present in different groups 3A, 4A, 5A, 6A, 7A, and 8A.
• The non-metals of 5A, 6A, 7A form anions with a negative charge in order to complete their octet.
• For these three group non-metals, it is easy to get 3, 2, and 1 electron than giving 5, 6, and 7 electrons respectively.

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