Question

an atom of magnesium has 12 protons and 12 electrons. if the atom loses 2 electrons, what will be the charge on the ion that forms?

Answer 1

Answer: +2

Step-by-step explanation:

It would be positive/plus 2 because electrons are negative. Think of it this way, if you subtract a negative, the answer is would be positive. (Ex: 3-2=1 because you are taking away 1 but if it were 3-(-2) it would be positive 5 bc it 2 negatives cancel each other and make a positive answer)

Answer 2

It would have a positive two charge (+2).
12+(-12)=0
12+(-10)=2
