Question 6 • Chemistry

Which statement is generally true about CaCl sub 2 ?

Answer
A
It has only covalent bonds between the atoms.
B
Its bonds are formed by large differences in electronegativity.
C
It has only metallic bonds between the atoms.
D
Its bonds are formed by small differences in electronegativity.

Explanation

Calcium is a metal and chlorine is a nonmetal, so calcium transfers electrons to chlorine atoms, forming Ca²⁺ and Cl⁻ ions. This ionic bonding is associated with a large difference in electronegativity, so the statement that its bonds are formed by large differences in electronegativity is correct.
