When the number of protons in an atom changes the atom's atomic number. If the atomic number of an atom is changd, the atom itself is changed into a different element. Protons determine the charge of the nucleus of an atom because they carry a positive electrical charge.
The atom is the smallest unbreakable unit that defines the chemical elements and their isotopes. Every substance, be it solid, liquid, gas, or plasma is made up of atoms. The size of atoms is measured...
