Protons are small subatomic particles found in the nucleus of atoms.

They have a positive charge.                                                                                                                                           

The number of protons in an atom of an element is the atomic number.

The atomic number is used to identify an atom.

Adding or removing protons from the nucleus of an atom creates a different element.

For example, removing one proton from an atom of oxygen creates a nitrogen atom. Add a proton to hydrogen and you make helium!
