Question

Which of the following atom(s) always exists in pairs (never alone) and is considered a

diatomic molecule? Choose all that apply.

Answer 1

Diatomic molecules consist of two atoms bonded together. In contrast, monatomic elements consist of single atoms (e.g., Ar, He). Many compounds are diatomic, such as HCl, NaCl, and KBr. Diatomic compounds consist of two different elements. There are seven pure elements that form diatomic molecules.
