A species with 12 protons and 10 electrons is

Question

Quizplus · Accepted Answer

The element with 12 protons is magnesium (Mg). However, Mg typically has 12 electrons to balance the charge of the protons. The species described in the question has 10 electrons, indicating that two electrons have been lost (or possibly gained, if it is an ion). Therefore, the correct choice is C: Mg²⁺. The addition of sulfur (S) with a charge of -1 and phosphorus (P) with a charge of +1 balances the overall charge of the species and accounts for the missing two electrons. The notation "S1" and "P0" indicate the neutral form of these elements.
