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 na lose their outer - shell electron in their 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 (Group 1A) have one valence electron. When they lose this electron, they achieve a stable electron configuration similar to the noble gases (Group 8A), which have full valence shells.

Answer:

D. 8A
