Why do atoms exchange or share electrons during bonding?

Question

A. to attract an ion with the opposite charge
B. to have eight inner level electrons
C. to obtain a full outer electron shell
D. to become neutral

Answer 1

Atoms exchange or share electrons during bonding primarily to achieve a full outer electron shell. This is often described by the octet rule, where atoms tend to gain, lose, or share electrons to have eight electrons in their outermost shell, leading to a more stable electron configuration.

Therefore, the correct answer is:

C. to obtain a full outer electron shell
