What is meant by dative covalent bond?

Question

For answering chemistry questions

Answer 1

Co-ordinate or Dative covalent bonding is where one atom gives both of the shared electrons in the bond.
Instead of each a tom giving an electron, one atom gives electrons that are shared.

Example of a substance that is formed through co-ordinate or dative covalent bonding is ammonium ions (NH4+). That is Ammonia (NH3+) plus hydrogen ion (H+).
