We cannot describe the shape and geometry of the formula units of ionic compounds because ionic bonds are

A

very strong

B

nondirectional

C

formed through exchange of electrons

D

very rare

Text Solution

Verified by Experts

The correct Answer is:
B
In ionic compounds, positive and negative ions attract each other through their electrostatic field which is nondirectional. As a result, each ion interacts with many ions of opposite charge and there are no discrete ion pairs.
