Study Notes
Polyatomic Elements Overview
- Polyatomic elements consist of molecules made of two or more atoms of the same element.
- They exist in various forms and play significant roles in chemistry and various scientific applications.
Key Polyatomic Elements
- Arsenic (As₂): Known for its toxicity and used in various alloys and semiconductor applications.
- Astatine (At₂): A rare element that is radioactive and has potential uses in targeted alpha-particle cancer therapy.
- Bromine (Br₂): A reddish-brown liquid at room temperature, used in flame retardants and pesticides.
- Chlorine (Cl₂): A greenish-yellow gas, essential in disinfection processes and water treatment.
- Fluorine (F₂): A highly reactive pale yellow gas, used to make fluoride compounds for dental health and in various industrial applications.
- Hydrogen (H₂): A colorless gas, the most abundant element in the universe, crucial for fuel cells and as a potential clean energy source.
- Iodine (I₂): A violet-black solid that sublimates easily, used in antiseptics and as a nutrient for thyroid health.
- Nitrogen (N₂): A colorless, odorless gas that makes up about 78% of Earth's atmosphere, vital for the production of fertilizers and explosives.
- Oxygen (O₂): A colorless gas essential for respiration in living organisms and involved in combustion processes.
- Phosphorus (P₄): Exists in several allotropes, used in fertilizers, detergents, and chemical syntheses.
- Sulfur (S₈): A yellow solid, used primarily in fertilizers, fungicides, and in the production of sulfuric acid.
- Antimony (Sb₄): A metalloid used in flame retardants and alloys.
- Selenium (Se₈): An essential trace element with applications in electronics, glassmaking, and as an antioxidant in dietary supplements.
