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. Atom vs Molecule. An atom is the smallest unit of an element. All atoms of a single element contain the same number of protons.

en.wikipedia.org/wiki/MoleculeFor example, hydrogen and oxygen exist as two-atom molecules. Other elements also exist naturally as diatomic molecules—a molecule with only two ato ms (Table \(\PageIndex{1}\)). As with any molecule, these elements are labeled with a molecular formula, a formal listing of what and how many
