Answer:
It will have "+2" charge.
Explanation:
The charge on a neutral atom is zero as it has same number of electrons and protons.
an atom develops a charge if it loses or gain electrons.
If it loses electrons (thus will have less number of electrons than protons) than positive charge is developed
If it gains electrons , a negative charge is developed.
Is the given ion, there are four protons and two electrons, so it must have lost two electrons thus it will have a dipositive charge.
