उत्तर
Covalent compounds are compounds that are formed by the sharing of electrons between two or more atoms.
Example: Hydrogen (H2) is a covalent compound, where each hydrogen atom shares one electron to form a stable compound.

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.
