The halogens (Group 17) include fluorine, chlorine, bromine, iodine, and astatine. Highly reactive, they readily gain an electron to form −1 anions. They form salts when reacting with metals (e.g., NaCl) and can also participate in covalent bonding. Halogens are used for disinfection, etching, and as precursors in organic synthesis. Their chemical behavior is influenced by atomic size and electronegativity, with fluorine being the most reactive element.
