Scandium-45 refers to an isotope of scandium. The number 45 represents the atomic mass number, which is the sum of protons and neutrons in the nucleus of an atom.

1. Identify the atomic number of Scandium. The atomic number of Scandium (Sc) is 21, which means it has 21 protons.

2. Subtract the atomic number from the atomic mass number to find the number of neutrons. So, 45 (atomic mass number) - 21 (number of protons) = 24.

Therefore, a neutral atom of Scandium-45 has 24 neutrons.
