How I would explain this to a student:"It is important to first know what the total marks for each answer is. 2 marks means the examiner requires 2 points. The question also states explain in terms o...

An ionic bond is the electrostatic attraction between two oppositely charged ions to form an ionic compound. The greater the charge of an ion the stronger the ionic bond as the attraction between the posi...
