Question

18.When magnesium combines with chlorine, it loses 2 electrons. What is the charge of magnesium?Select one:a. +2b. 0c. -2d. -4

Answer 1

Answer:

$A\text{ : +2}$

Explanation:

Here, we want to get the charge of magnesium

Magnesium is an atom that has 12 protons and 12 electrons

Losing 2 out of the 12 electrons means it would be left with 12 protons and 10 electrons

What that means is that it would be having an excess of 2 protons

This gives it a charge of +2
