Which of the following would be an ion with a double positive charge?
A)an Mg atom that gains two electrons
B)an Mg atom that gains one electron
C)an Mg atom that loses two electrons
D)an Mg atom that loses one electron
E)none of the above

Question

Quizplus · Accepted Answer

When a neutral Mg atom loses two electrons, it becomes Mg2+. This ion has a double positive charge, as there are now two more protons than electrons in the atom. Option A is incorrect because gaining electrons would make Mg negatively charged. Option B is incorrect because gaining one electron would only make Mg1-. Option D is incorrect because losing one electron would only make Mg1+. Option E is incorrect because there is a correct option - C.
