How many protons,electrons,and neutrons,respectively,does ⁴⁰Ca²⁺ have?

Question

Quizplus · Accepted Answer

The given symbol represents a calcium ion with a charge of +2 (Ca^2+). Calcium (Ca) has an atomic number of 20, which means it has 20 protons and, in its neutral state, 20 electrons. However, since it has a +2 charge, it has lost 2 electrons, leaving it with 18 electrons. The mass number (P) is 40, which is the sum of protons and neutrons. Therefore, to find the number of neutrons: 40 (mass number) - 20 (protons) = 20 neutrons.
