please add my answer to the brainelist answers and follows up me
A molecule is two or more atoms bonded together to form a single chemical entity. Each atom carries a certain number of electrons that orbit around the nucleus. The nucleus consists of protons and neutrons, of different numbers in different elements. The electrons that orbit the nucleus exist in various clouds, or valence shells. These shells prefer to have specific numbers of electons, depending on the shell. Sometimes, one atom will give away electrons to another atom. These atoms both change in electrical charge and become ions. One will be positive and one will be negative. These opposite electrical effects attract each other and form ionic bonds. These bonds to not make a molecule, and the ions can be easily separated. However, sometimes atom share electrons.
