Question

Which property of chlorine explains why it is likely to form a compound with an alkali metal

a. it will accept one electron to complete its outer shell
b. it will accept two electrons to complete its outer shell

Answer 1

a. It will accept one electron to complete its outer shell.

Step-by-step explanation:

Chlorine is in Group 17, so it has seven valence electrons, one short of a complete outer shell.

Thus, it will accept an electron from sodium to complete its outer shell.
