Question

what is the difference between molecules and ions​

Answer 1

Molecules are groups of two or more atoms that are chemically bonded. Ions are atoms or molecules that have gained or lost one or more of their valence electrons and therefore have a net positive or negative charge. An atom can be an ion, but not all ions are atoms.

Answer 2

Molecules are neutral particles made of two or more atoms bonded together. An ion is a positively or negatively charged particle
