A molecule is a covalently bonded substance containing 2 or more different atoms. Pb and Ar are atoms/elements. NaF is ionically bonded. CH4 is covalently bonded, and also has 2 different types of atoms...therefore it is the molecule.

CH4 is the molecule because it is the only covalent compound. NaF is ionic and Pb and Ar are elements.

First you ask us which substance is an element, and now which substance is a molecule? Do your own homework.
