Question: which one of the following elements give polyatomic molecules?
Answer: Any molecule that contains more than 2 atoms is polyatomic. So that would be ozone (O3), etc. Anything that consists of two or more atoms is called molecular, for example oxygen (O2), nitrogen (N2), ozone (O3), carbon dioxide (CO2), methane (CH4), benzene (C6H6), and way bigger like rotaxane or proteins or polymers.
