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