Study Notes
Properties of Nonmetals
- Nonmetals are dull, cannot be hammered into sheets or drawn into wires, and are poor conductors of heat and electricity.
- Materials containing phosphorus, a nonmetal, can conduct electricity.
- Phosphorus is used in fertilizers and match tips.
- Humans require phosphorus, found in seafood, chicken, and nuts.
- Chlorine, another nonmetal, is used in disinfectants, bleach, and water purification.
Importance of Phosphorus in Life
- Phosphorus is essential to human health, found in seafood, chicken, and nuts.
Nonmetals and Their Properties
- Nonmetals occupy the right side of the periodic table and exist in solid, liquid, or gaseous states at room temperature.
- Examples of solid nonmetals include phosphorus (P) and iodine (I).
- Bromine (Br) is a liquid nonmetal.
- Oxygen (O2) and nitrogen (N2) are gaseous nonmetals that make up the Earth's atmosphere.
Composition of the Atmosphere
- Earth's atmosphere is composed primarily of nitrogen (N2) at 78% and oxygen (O2) at 21%.
- The remaining 1% consists of other gases.
Examples of Nonmetals
- Nonmetals exist in various states:
- Boron (B2) is a solid.
- Iodine (I2) exists as crystals.
- Bromine (Br2) is a liquid.
