검증된 단계별 안내1
Recall that diatomic molecules consist of only two atoms, which can be either two atoms of the same element or two different elements bonded together.
Identify the molecules given: N2, H2, O2, and CO2, and note the number of atoms in each molecule.
N2, H2, and O2 each consist of two atoms bonded together, making them diatomic molecules.
CO2 consists of one carbon atom and two oxygen atoms, totaling three atoms, so it is not diatomic but rather a triatomic molecule.
Therefore, the molecule that is NOT diatomic among the options is CO2.
