Which of the answer choices correctly predicts the charge that would be present on a magnesium (Mg) ion, as shown in the periodic table?
2+
1+
1-
2-
is it a?
Well Mg is in the second column on the periodic table mean it would have a +2 charge.
so is it right?
To determine the charge of a magnesium (Mg) ion, we can refer to the periodic table.
Magnesium is located in group 2 (or group IIA) of the periodic table. Elements in group 2 are called alkaline earth metals. These metals tend to lose two electrons to form positive ions with a 2+ charge.
Therefore, the correct answer choice that predicts the charge on a magnesium (Mg) ion is 2+. So, the correct option is "a".
