Question

define molecules. name the molecules which are Monoatomic​

Answer 1

Answer:

Monoatomic (monatomic): A molecule composed of just one atom, and lacking any covalent bonds. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are all monoatomic, whereas most other gases are at least diatomic.

Answer 2

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are all monoatomic
