Detailed explanation-1: -If the difference between the electronegativities is large, the more electronegative atom will take the bonding electrons completely away from the other atom (electron transfer will occur) and the bond will be ionic.

Detailed explanation-2: -One way to predict the type of bond that forms between two elements is to compare the electronegativities of the elements. In general, large differences in electronegativity result in ionic bonds, while smaller differences result in covalent bonds.

Detailed explanation-3: -The greater the difference in electronegativity, the more polarized the electron distribution and the larger the partial charges of the atoms.

Detailed explanation-4: -In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

Detailed explanation-5: -There are few factors that cause the formation of ionic bonds; one of them is the large differences in electronegativity of atoms, which attract other atoms for the transfer of their electrons. This chemical interaction of electrons creates a strong bonding between the atoms as compared to other types of bonds.
