Question

What are the ions present in $\mathrm{NaCl}$?

Answer 1

Sodium chloride $\left(\mathrm{NaCl}\right)$:

• Sodium chloride is commonly called table salt.
• It is an ionic compound comprised of sodium and chlorine atoms.

Formation of sodium chloride:

• When sodium atoms $\left(\mathrm{Na}\right)$ interact with chlorine atoms $\left(\mathrm{Cl}\right)$, sodium chloride is formed.
• Sodium will donate an electron $\left(-\mathrm{ve}\right)$ to chlorine.
• Due to the transfer of electrons, sodium will become positively charged while chlorine will become negatively charged.
• Sodium will become $\left({\mathrm{Na}}^{+}\right)$ while Chlorine becomes $\left({\mathrm{Cl}}^{-}\right)$.
• Hence, ions present in $\mathrm{NaCl}$ are: ${\mathrm{Na}}^{+}$ and ${\mathrm{Cl}}^{-}$
