Question
Calcium (Ca) has an atomic number of 20. It can form an ion by losing 2 electrons. What would its charge be?A.2+B.22C.18D.2–
Solution
The charge would be A. 2+. This is because when an atom loses electrons, it becomes a positive ion. Since Calcium loses 2 electrons, it would have a charge of 2+.
