Question

The overall charge on the 'sodium chloride' compound formed by the combination of $C{l}^{-}$ ion and $N{a}^{+}$ ion is

• A. -1 charge
• B. +1 charge
• C. + 2 charge
• D. None of these.

Answer 1

The correct option is D

None of these.

In the formation of NaCl compound, an equal number of $N{a}^{+}$ and $C{l}^{-}$ ions combine. Hence, the +1 charge of $N{a}^{+}$ ions is cancelled by -1 charge on $C{l}^{-}$ ions. $NaCl$ compound is electrically neutral with net zero charges.
