Identify the incorrect statement and correct them.

  1. Like covalent compounds, coordinate compounds also contain charged particles (ions). So they are good conductors of electricity. 
  2. Ionic bond is a weak bond when compared to Hydrogen bond.
  3. Ionic or electrovalent bonds are formed by mutual sharing of electrons between atoms. 
  4. Loss of electrons is called Oxidation and gain of electron is called Reduction.
  5. The electrons which are not involved in bonding are called valence electrons.
