Answer:

No. Multiple atoms of a single element can sometimes form molecules.

Explanation:

It's most often diatomic molecules of an element like #"H"_2# for hydrogen, #"N"_2# for nitrogen, or #"O"_2# for oxygen. But sometimes a single element can form molecules with more atoms, like #"O"_3# for ozone (another molecular form of oxygen) or #"S"_8# for sulfur. Single atoms of noble gases like atgon (#"Ar"#) may also be considered as molecules.
