Non-metals are elements that generally lack metallic properties. They usually have lower melting and boiling points compared to metals and are poor conductors of heat and electricity.
**Examples of Non-metals:**
1. **Hydrogen (H):** A colorless gas and the lightest element.
2. **Oxygen (O):** Essential for respiration and combustion.
3. **Nitrogen (N):** Constitutes a large portion of Earth's atmosphere.
4. **Carbon (C):** Fundamental in organic compounds and the basis of life.
5. **Sulfur (S):** Found in various compounds, including amino acids.
6. **Phosphorus (P):** Important in biological molecules like DNA.
7. **Fluorine (F):** Highly reactive, a component of fluoride compounds.
8. **Chlorine (Cl):** Used for water purification and in various chemicals.
9. **Bromine (Br):** A reddish-brown liquid halogen.
10. **Iodine (I):** Often used in medical applications and as a dietary supplement.
These elements play crucial roles in various chemical reactions and natural processes, contributing to the diversity and complexity of the natural world.
A nonmetal is a chemical element that mostly lacks metallic properties. Seventeen elements are generally considered nonmetals, though some authors recognize more or fewer depending on the properties considered most representative of metallic or nonmetallic character.
