1. Hydrogen Halides: These compounds form when hydrogen reacts with a halogen (Group 17 element) such as fluorine, chlorine, bromine, or iodine. Examples:
- Hydrogen fluoride (HF)
- Hydrogen chloride (HCl)
- Hydrogen bromide (HBr)
- Hydrogen iodide (HI)
2. Metal Oxides: These compounds form when a metal reacts with oxygen (Group 16 element). Examples:
- Carbon dioxide (CO2)
- Sulfur dioxide (SO2)
- Nitrogen dioxide (NO2)
3. Water (H2O): Water is a covalent compound formed by the reaction of hydrogen and oxygen.
4. Ammonia (NH3): Ammonia is a covalent compound formed by the reaction of nitrogen and hydrogen.
5. Carbon Monoxide (CO): Carbon monoxide is a covalent compound formed by the reaction of carbon and oxygen.
6. Nitrous Oxide (N2O): Nitrous oxide is a covalent compound formed by the reaction of nitrogen and oxygen.
In general, covalent compounds are characterized by the sharing of electrons between non-metal atoms. The resulting molecules are held together by covalent bonds, which are strong chemical bonds formed when atoms share electrons.
