Study Notes
Halogen Classification
- Not a Halogen: Elements like noble gases (e.g., helium, neon) are not classified as halogens.
States at Room Temperature
- Common Characteristic: Halogens exist in different states at room temperature; fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.
Reactivity of Halogens
- Least Reactive Halogen: Astatine is the least reactive halogen in the group.
Formation of Salts
- Salt Formation: Halogens easily form salts with metals due to their high electronegativity and tendency to gain one electron.
Electronegativity
- Highest Electronegativity: Fluorine has the highest electronegativity of all elements, making it extremely reactive.
