There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.

Answer 2

Answer:

(a) This statement is wrong that covalent bonds are formed between two metals. Covalent bond are formed between only e 14th groups compound which has four electron in their outermost shell. for example CO2

(b) This statement is also wrong that ionic compounds formed between two metals. ionic compound are found by one metal or one nonmetal .For example NaCl in which and a is metal or Cl is non metal .

(c) This statetment is also wrong covalent bonds are formed between a metal and a nonmetal. covalent bonds are always formed between two nonmetals.

(d) This statement is correct
