What would the result be of adding one proton to an atom​

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.

Explanation:

neutrons are in the middle of the atom and the electrons, which are much smaller.
