Chlorine in domestic instance and flourine in atmosphere.
The most common halogen on the periodic table would have to be either chlorine or iodine.
Iodine
Halogen refrigerants are also known as coolant chemicals, which can cause ozone damage. A great example of a common halogen refrigerant would be Freon.
highly reactive with alkali metals and alkaline earth metals
A halogen carrier is a compound that helps facilitate halogenation reactions by carrying or transferring halogen atoms to other molecules. This process is commonly used in organic chemistry to introduce halogen atoms (such as chlorine, bromine, or iodine) into organic compounds. Common examples of halogen carriers include N-chlorosuccinimide (NCS) and N-bromosuccinimide (NBS).
Halogen molecules are diatomic, meaning they consist of two atoms. The most common halogen molecules include fluorine (F₂), chlorine (Cl₂), bromine (Br₂), iodine (I₂), and astatine (At₂). These molecules are covalently bonded, where two atoms of the same halogen share a pair of electrons. Halogens are known for their reactivity and tendency to form compounds with other elements.

The different types of halogen bulbs available in the market include standard halogen bulbs, halogen floodlights, halogen spotlights, and halogen capsule bulbs.
If the halogen is in ionic form in the compound, the general name is "halide". Common salt, with formula NaCl, is a familiar example. There are also many other compounds of halogens in which the halogen participates in a covalent bond rather than forming an ion.
Any element, other than a halogen is - by definition - not a halogen and so it does not have a halogen and that is less than one halogen.
Yes, I (iodine) is a halogen.
Halogen compounds are commonly used as disinfectants, bleaching agents, and in the production of pharmaceuticals and plastics. They are also used in water treatment, as flame retardants, and in the manufacturing of electronic components.
