Explanation:
The atomic number refers to the number of protons in the nucleus of an atom. We identify an element by its atomic number.
When the atomic number of an atom of an element is changed, we have changed the identity of that atom and transformed it into an atom of a different element.
For example, if we add a proton to a sodium atom, we create a magnesium atom. If we remove a proton from a sodium atom, we create a neon atom.
