An ionic bond is formed by the transfer of electrons from electronegative elements to electropositive elements.
Some examples of compounds where ionic bonds are formed
- Sodium Chloride (NaCl)
- Magnesium Chloride (MgCl₂)
- Potassium Iodide (KI)
A covalent bond is formed by the sharing of electrons between 2 atoms.
Some examples include :
- Methane (CH₄)
- Ammonia (NH₃)
- Water (H₂O)
