Question

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

Explanation:

Calcium chloride (\(CaCl_{2}\)) es un compuesto iónico. Los compuestos iónicos se forman entre un metal (calcio, en este caso) y no - metales (cloro). La diferencia de electronegatividad entre el calcio (electronegatividad \(\approx 1\)) y el cloro (electronegatividad \(\approx 3\)) es grande (\(\Delta EN=3 - 1=2\)). En los enlaces iónicos, la transferencia de electrones se debe a diferencias importantes en la electronegatividad.

Answer:

Its bonds are formed by large differences in electronegativity.
