    The atomic number of magnesium is 12, the number of protons is 12, the number of masses is 24, and the number of neutrons = mass number - number of protons = 24-12 = 12

    The atomic number of aluminum is 13, the number of protons is 13, the mass number is 27, and the number of neutrons = mass number - number of protons = 27-13 = 14

    The atomic number, non-atomic number, is the number of an element in a non-monoatomic state. Magnesium aluminum is a monoatomic state with no atomic number. The number of protons in the magnesium nucleus is 12, and the number of neutrons is 12. There are 13 protons and 14 neutrons in the aluminum nucleus.
