"Its bonds are formed by large differences in electronegativity" is the statement among the choices given in the question that is generally true about CaCl2. The correct option among all the options that are given in the question is the third option or the penultimate option. I hope that the answer has helped you.

Answer:

Its bonds are formed by large differences in electronegativity.

Explanation:

The electronegativity of the elements present in the given compound are:

Calcium:1

chlorine: 3.16

thus the difference between calcium and chlorine is 2.16. which is considered a very large difference making the bond between calcium and chlorine purely ionic.

The other statements are false

1) It has only metallic bonds between the atoms.: there is no metallic bond. metallic bonds are present between metal atoms.

2) It has only covalent bonds between the atoms.: the covalent bond are formed between non metallic elements.

3) as calculated the difference is large thus this is also wrong Its bonds are formed by small differences in electronegativity.
