Question

What is the charge of a magnesium ion that has lost its two valence electrons?
+1
+2
-1
-2

Answer 1

Answer: +2

Explanation:

The answer would be +2. For every electron lost, the element would gain a positive charge, such as +3 or +5. For example, oxygen has 8 total electrons. If it lost say, 4 of them, then oxygen would have a positive charge of +4. Hope this helped you!
