INTRODUCTION 0:07
Ionic bonding happens between metal and non-metals. The metal will lose electrons and it will become into positive ions. the non-metal will gain electron and it will become into negative ions. By becoming into positive and negative ions, these atoms attain full outer-shell of electron. The positive ions and the negative ion attract each other by electrostatic attraction.

DRAWING NaCl IONIC BOND 0:42
Sodium has one electron in the outer-shell so this electron is lost which makes the sodium to have full outer-shell of electron. The sodium metal atom becomes into a positive ion. Chlorine has seven electrons in the outer shell so it gains electron from the sodium, therefore there is transfer of electron from metal to non-metal. Chlorine atom becomes into a negative ion as it has gained electron. The positive sodium ion and the negative chloride ion attract each other.

DRAWING MgO IONIC BOND 4:04
For MgO there is transfer of 2 electrons. This is because Mg has 2 electrons in the outer-shell and oxygen has 6 electrons in the outer shell. In order to have full-shell, Mg has to lose those 2 electrons and whereas the O has to gain these 2 electrons. At the end, Mg becomes into a positive ion with the charge of +2 and the oxygen becomes into a negative ion with the charge of -2.
