Question

Which type of bond forms on the transfer of electrons?

• A. Ionic Bond
• B. Metallic Bond
• C. Hydrogen Bond
• D. Covalent bond

Answer 1

Answer: (A)

Ionic Bond

Ionic bond involves a complete transfer of electron. For eg. in $NaCl$, $Na$ gives one of its electron to $Cl$.

$Na\to N{a}^{+}+e^{-}$

$Cl+e^{-}\to C{l}^{-}$ and $N{a}^{+}$ and $C{l}^{-}$ being oppositely charged attracts each other.

Hence $NaCl$ (ionic compound) is formed by transfer of electron.
