Group VII elements, also known as the halogens, include fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The properties of these elements typically include:
- Reactivity: Generally very reactive, with reactivity decreasing down the group.
- State at Room Temperature: Varies; fluorine and chlorine are gases, bromine is a liquid, and iodine is a solid.
- Electronegativity: High electronegativity, decreasing down the group.
- Melting and Boiling Points: Increase down the group due to stronger van der Waals forces as the molecular size increases.
- Color: They have distinct colors; for example, fluorine is yellow-green, chlorine is yellow-green gas, bromine is a reddish-brown liquid, and iodine appears as a purple solid.
