Scandium's, or Sc's, atomic number is 21. Its most common isotope has an Atomic Mass of 45. Since an electrically neutral atom's atomic number is equal to its number of protons as well as its number of electrons; and since the number of neutrons in a particular isotope of an atom is equal to its atomic mass minus its atomic number, the number of neutrons of the most common isotope of neutral scandium is 45 - 21 = 24.
