The following table summarizes the various properties of halogens.
Biological lifeforms may experience harmful effects if they are exposed to either large quantities of halogens, or to moderate quantities for long durations.Īll halogen characteristics can be attributed as occurring due to the innate physical and chemical properties that the elements of this group possess in common. Halogens get their high tendency to react with other matter due to high levels of electronegativity of their atoms, which is a result of the high effective nuclear charge of all halogen atoms. On reacting among themselves within the halogen group, these elements form diatomic inter halogen compounds. 
All halogen elements form hydrogen halides, which are very strong acids, when they combine with hydrogen, and form binary compounds. This is proved by the fact that when kept under room temperature and normal pressure, astatine and iodine take the form of solids, bromine appears as a liquid, and chlorine and fluorine occur as gases. As mentioned previously, halogens are the only elemental group in the entire periodic table, which is composed of elements that belong to all three classical states of matter (solid, liquid, and gas). This is because halogen elements tend to create salt when they come in contact with the metals and combine with them to form compounds. Most halogen ions and atoms can be found in combination with other compounds present in the sea or mineral water. They are usually found occurring as compounds or as ions. Due to this tendency towards high reactivity, the halogens cannot exist in the environment as pure elements. All these elements are extremely reactive. A unique characteristic of halogens is that it is the only group in the entire periodic table that is composed of elements that belong to all three classical states of matter (solid, liquid, and gas), when kept under standard conditions of pressure and temperature. Ununseptium is not a naturally occurring element, and is also believed to be a halogen. The members that are a part of the halogen family include chlorine, fluorine, iodine, bromine, and astatine. #Halogen symbol series#
