It should also be noted that – “Most transitional metals have two valence electrons, but may have a larger range of apparent valence electrons. Therefore, a thorium atom has ninety protons and ninety electrons. The number of neutrons in an atom can be determined by the difference between the atomic mass and the number of protons. The difference between the mass number of the thorium atom and the number of protons is one hundred forty-two.
