Sep 12, 2020 · A molecule is an electrically neutral group of atoms held together by chemical bonds. A molecule is defined as an electrically neutral group of two or more atoms connected by chemical bonds. Here are examples of molecules and a look at the difference between a molecules, compounds, and ions.
According to this less common definition, a molecule is a group of covalently bound atoms of the same element only. In the rest of this article, we will stick to the broader definition of molecule because it is more common.

Jul 18, 2022 · By. Anne Marie Helmenstine, Ph.D. Updated on July 18, 2022. The terms molecule, compound, and atom can be confusing! Here's an explanation of what a molecule is (and is not) with examples of common molecules. Molecules form when two or more atoms form chemical bonds with each other.
- Anne Marie Helmenstine, Ph.D.
A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Jul 18, 2022 · A molecule is the smallest part of a substance that has the physical and chemical properties of that substance. In some respects, a molecule is similar to an atom. A molecule, however, is composed of more than one atom.
