Question

Why do atoms exchange or share electrons during bonding?

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

Answer 1

Atoms exchange or share electrons during bonding primarily **to obtain a full outer electron shell**. This concept is often referred to as the "octet rule," which states that atoms tend to bond in a way that they have eight electrons in their valence (outer) shell, leading to greater stability. By achieving a full outer shell through the sharing or transferring of electrons, atoms can attain a more stable electronic configuration, similar to that of noble gases.
