Question

what is the difference between atom and molecule ​

Answer 1

Explanation:

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

Atom refers to the smallest constituent unit of a chemical element. Molecules refer to a group of two or more atoms that are held together due to chemical bonds.

Answer 2

Answer:

An atom is the smallest unit (considered even it has electrons and protons which are way more small) of all the materials in this world and a molecule is basically made up of group of atoms for example:

"H" means hydrogen atom but "H2" means hydrogen molecule as it is made by the combination of 2 hydrogen atoms.
