A molecule made up of two atoms of two different elements is best described as which type of molecule?
AHomodiatomic molecule
BHeterodiatomic molecule
CHomotriatomic molecule
DHeterotriatomic molecule
Answer & Solution
Correct answer: B. Heterodiatomic molecule
1. Atomicity is the number of atoms in a molecule; two atoms means diatomic.
2. Atoms of different elements make the molecule heteroatomic.
3. Two atoms of different elements together give a heterodiatomic molecule (e.g. HCl).
