Verified step by step guidance1
Identify the chemical formula of the molecule in question, which is CO2.
Count the number of atoms present in the molecule. CO2 consists of 1 carbon atom and 2 oxygen atoms.
Add the number of atoms together: 1 (carbon) + 2 (oxygen) = 3 atoms in total.
Understand the definitions: 'Monatomic' refers to a molecule with one atom, 'Diatomic' refers to a molecule with two atoms, 'Triatomic' refers to a molecule with three atoms, and 'Polyatomic' refers to a molecule with more than three atoms.
Based on the count of atoms in CO2, determine that the term 'Triatomic' correctly applies to this molecule, as it contains three atoms.
