Question 13

Alkali metals react very readily with halogens and form ionic compounds such as table salt (NaCI) and many others. Which of the following explanations most completely describes why these two families of elements reacts readily?

Accepted Answer

The alkali metals have one valence electron, and the halogens are one short of an octet.
