Covalent bond is formed ...................Becoz the e- diff is greater than 1.8. So it is covalent
DILIP
Ionic bonding occur when there is complete transfer of the electrons in the bond. This type of bonding does not lead to the formation of molecule, but rather consists of a stacking of a great many ions, such that an overall neutral lattice is formed. Substances such as NaCl and MgCl2 are examples. Generally, electronegativity differences of 1.8 or greater lead to ionic bonding. The electronegativity difference is so great that one atom can attract the electrons enough to "take" them from the other atom.
