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 mg²⁺? 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 by the gain or loss of electrons. A magnesium ion with a charge of +2 ($Mg^{2 +}$) means it has lost 2 electrons. Neutrons are related to isotopes, not ion - formation for a given charge.
Answer:
It must lose two electrons and become an ion.
