Question

when atoms react, they often lose, gain, or share electrons to form a more stable version of themselves. for example, alkali metals such as lithium lose their outer - shell electrons in these reactions to form compounds. the electron configuration of alkali metals would then resemble those of which group of the periodic table in the compounds they form?
a 1a
b 2a
c 7a
d 8a

Explanation:

Alkali metals in group 1A lose their single outer - shell electron to form compounds. After losing this electron, their electron configuration resembles that of the noble gases in group 8A, which have a full outer - shell and are very stable.

Answer:

D. 8A
