Question

The nonmetals in groups 5A, 6A, and 7A...
a. lose electrons when they form ions
b. form positively charged ions
c. form ions with charges of 3-, 2-, and 1-, respectively
d. form ions with a numerical charge equal to their group number

Answer 1

a. nope, they gain electrons because it's easier to fill the shell by adding electrons since they already 5/6/7 out of 8
b. again, they gain electrons so they're negatively charged ions
c. yup! in 7A, they gain 1 electron to have 8 electrons in the shell and become 1-. 6A becomes 2- and 5A becomes 3-
d. nope
