Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom. The isotope with mass number 60 contains (60 - 27) or 33 neutrons per atom. Since cobalt has an atomic number of 27, any isotope of it contains 27 protons and 27 electrons per atom.
Look at the periodic table. Mg is number 12, so it has 12 protons and 12 electrons. The +2 charge of a magnesium ion means the number of protons is 2 more than the number of electrons. To become a magnesium ion, 2 electrons are removed from the outer shell of the magnesium atom. The Mg +2 ion contains 12 protons and 10 electrons = +12 + -10 = +2 charge. The number of protons cannot change, unless the atom is radioactive. The nuclei of radioactive elements emit an alpha particle, which is composed of 2 protons and 2 neutrons. This process is called transmutation.
