the simple model below is a neutral magnesium (mg) atom with the elements most common mass number. what must happen to an atom of magnesium in order to become a magnesium ion mg+2? it must lose two neutrons and become a different isotope. it must gain two neutrons and become a different isotope. it must lose two electrons and become an ion. it must gain two electrons and become an ion.

the simple model below is a neutral magnesium (mg) atom with the elements most common mass number. what must happen to an atom of magnesium in order to become a magnesium ion mg+2? it must lose two neutrons and become a different isotope. it must gain two neutrons and become a different isotope. it must lose two electrons and become an ion. it must gain two electrons and become an ion.

Answer

Brief Explanations:

An ion is formed when an atom gains or loses electrons. A positive - charged ion ($Mg^{2 + }$) is a cation, which is formed by losing electrons. Since the charge is + 2, two electrons must be lost. Neutrons are related to isotopes, not ion - formation.

Answer:

It must lose two electrons and become an ion.
