a) Using the electronic configurations, explain how magnesium atom combines with oxygen atom to form magnesium oxide by transfer of electrons. Magnesium (Mg) loses two electrons from its outermost shell and becomes Mg2+, while oxygen(O) gains two electrons to become O2- .
b) The ions present in Na2O are sodium ions (2Na+) and oxide ion O2-. The ions present in MgO are magnesium ion (Mg 2 +) and oxide ion O2- .
