An atom has an atomic number of 12 and a mass number of 25. Determine the number of protons, neutrons, and electrons in this atom, and identify the element.
The atomic number represents the number of protons in an atom, so this atom has 12 protons. The element with atomic number 12 is magnesium (Mg). In a neutral atom, the number of electrons is equal to the number of protons, so there are also 12 electrons.
