Halogen Properties We will look at some of the physical and chemical properties of Halogens Physical Properties The group of halogens is the only periodic table group that contains elements in all three familiar states of matter at standard temperature and pressure Fluorine (F) is a pale yellow gas Chlorine (Cl) is a greenish gas.

Halogen gas the gas inside of the halogen bulb combines with the tungsten vapor given off by the filament (the part that gets hot and emits light) If the temperature is high enough this vapor is redeposited on the filament recycling the tungsten and extending the bulb lifetime The bulb is able gets much hotter producing more light per unit of electricity compared to an incandescent.

The halogen lamp is also known as a quartz halogen and tungsten halogen lamp It is an advanced form of incandescent lamp The filament is composed of ductile tungsten and located in a gas filled bulb just like a standard tungsten bulb however the gas in a halogen bulb is at a higher pressure (78 ATM) The glass bulb is made of fused quartz.

Gases A halogen is a monovalent element on the Periodic Table which easily forms negative ions There are 5 such halogens fluorine chlorine bromine iodine and astatine but only iodine and bromine are used in lamps In a halogen light bulb the filament wears down shedding tungsten atoms over time These discarded atoms unite with the halogen gas.
