what is the difference between atoms or molecules

A neutral atom or molecule has to have the same number of protons than of electrons. If you have a positive charge, it is because the atom or molecule is one of several electrons short of a full set (atoms cannot lose protons, as they are tightly bound in the nucleus, and it takes nuclear reactor to change that).
A molecule is an entity that combines one or several atoms, not necessarily of the same element, together.

An electron is a negatively charged particle, and a proton is positively charged. Both of these, along with neutrons (which have no electric charge) If you have more protons than electons, the atom has a more positive charge, and more electrons will increase the negativity.
Atoms are the smallest form of matter, and make up molecules, the next smallest. For example, when two hydrogen atoms and one oxygen atom mix together, they make water, or H20.

If an atom or molecule gives away electrons, it is giving away negative charges. This leaves the atom or molecule with a positive charge.
Atoms are single units of an element. Molecules are composed of one or more atoms bonded together.

Protons = positive
Electrons = negative
If an atom/molecule is positive, it means it has more Protons than electrons. (more + than -)
