Part 1: The number of protons in an atom is equal to its atomic number. For Scandium (Sc), the atomic number is 21, so it has 21 protons.

Part 2: The number of neutrons in an atom can be found by subtracting the atomic number from the atomic mass number. For Scandium (Sc), the atomic mass number is 45 and the atomic number is 21. So, 45 - 21 = 24. Therefore, Scandium has 24 neutrons.

Part 3: In a neutral atom, the number of electrons is equal to the number of protons. So, a Scandium atom also has 21 electrons.
