ANSWER:

Solution 85E Step 1 of 5 Ionic bond is formed between metal and nonmetal due to transfer of electrons from metal to nonmetal. The electron can be transferred due to the great Electronegativity difference ( usually Electronegativity >1.9) that exists between two elements and results in the formation of oppositely charged ions: a cation (formed from metal) and an anion (formed from nonmetal). Covalent bond is formed between nonmetals due to sharing of electrons between the bonded atoms.In this case we can distinguish between “pure” covalent bond (01.9 we can expect an ionic bond, thus a total transfer of electrons from potassium to sulphur Potassium has one electron of valence. It can loose it to leave out its inner,
