2 of 10
What is meant by the term Ionic bond?
Strong electrostatic forces of attraction between two oppositely charged Ions.
3 of 10

Why do some Iona have higher melting?boiling points than others?
There are stronger bonds in one than the other due to the amount of electrons lost from one t the other.
