The Bond Between Sodium and Chlorine Atoms in Sodium Chloride

Question

The bond between sodium and chlorine atoms in sodium chloride is a(n)
A)hydrogen bond.
B)ionic bond.
C)polar covalent bond.
D)nonpolar covalent bond.

Accepted Answer

Sodium and chlorine have very different electronegativities, and in sodium chloride, sodium gives up an electron to chlorine. This results in the formation of two ions with opposite charges, which are attracted to each other through electrostatic force, forming an ionic bond.
