Which statement is generally true about cacl2?
it has only metallic bonds between the atoms.
it has only covalent bonds between the atoms.
its bonds are formed by large differences in electronegativity.
its bonds are formed by small differences in electronegativity.

Answer;

Its bonds are formed by large differences in electronegativity.

Explanation.

-Calcium chloride is an example of ionic compound that results from the transfer of electrons between calcium atom and chlorine atoms.

-Ionic bonding involves the transfer of electrons between atoms.These types of bonds require at least one electron donor and one electron acceptor. Conversely, in covalent bonds,atoms that have the same electronegativity share electrons because donating or receiving electrons is unfavorable.

-Therefore, ionic bonds are formed as a result of large differences in the electronegativity of the atoms involved.
