What is halogen? Halogens A halogen is one of the highly reactive elements located in group 17 of the periodic table. The halogens (in increasing atomic mass) are: fluorine, chlorine, bromine, … iodine, and astatine.he halogens or halogen elements are a series of nonmetal elements from Group 17 IUPAC Style (formerly: VII, VIIA, or Group 7) of the periodic table, comprising fluorine, F; c … hlorine, Cl; bromine, Br; iodine, I; and astatine, At. The undiscovered element 117, temporarily named ununseptium, may also be a halogen.

Nonmetals - Definition and Properties Technically the halogens and noble gases are nonmetals, but the nonmetal element group usually is considered to consist of hydrogen, carbon, nitrogen, oxygen, phosphorus, sulfur, and selenium.Properties.Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily.he nonmetals are located on the upper right side of the periodic table. Nonmetals are separated from metals by a line that cuts diagonally through the region of the periodic table containing elements with partially filled p orbitals.

Halogens on the Right You will often find them bonding with metals and elements from Group One of the periodic table. The elements in the column on the left each have one electron that they like to donate. We've just told you how reactive the halogens are. Not all halogens react with the same intensity or enthusiasm. Fluorine is the most reactive and combines with most elements from around the periodic table.

What are the physical properties of Halogens? As a group, halogens exhibit highly variable physical properties. Halogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature. The chemical properties are more uniform. The halogens have very high electronegativities.Fluorine has the highest electronegativity of all elements.alogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature.

The artificially created element 117 (tennessine, Ts) may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17. The symbol X is often used generically to refer to any halogen. The name 'halogen' means 'salt-producing'.

- As, the ability to gain electrons decreases down a group due to increase in atomic size and less nuclear pull .... So, it decreases down a group ..... among all non-metals halogens r most reactive bcoz of smallest size in period and high nuclear pull ..... So, fluorine is the most reactive non-metal ...... As, it is a halogen and is situated at the top of halogen group ....

Structure & Bonding The halogens (F, Cl, Br etc.) are one electron short of a valence shell octet, and are among the most reactive of the elements (they are colored red in this periodic table). In their chemical reactions halogen atoms achieve a valence shell octet by capturing or borrowing the eighth electron from another atom or molecule.

Halo Effect It seems as if known personal characteristics radiate a positive or negative halo (hence the name halo effect), influencing a person’s expectations about other as yet unknown qualities. Halo effects reflect the apparent belief that positive and negative characteristics occur in consistent patterns.

- Alkaline metals are reactive because they contain one electron in their outer shell. Halogens are reactive because they contain seven electrons in their outer shell. The closer the number is to one or seven, the more reactive the element is.

What are the physical properties of Halogens? They are found in all three states of existence. Here are some other physical properties of halogens that make them a very unique family of elements. Appearance Appearance wise fluorine exists as a pale yellow gas that is poisonous in nature, while chlorine is similarly poisonous but exists as a pale green colored gas.alogens range from solid (I2) to liquid (Br2) to gaseous (F2 and Cl2) at room temperature. The chemical properties are more uniform. The halogens have very high electronegativities. Fluorine has the highest electronegativity of all elements.

Halocarbon Many synthetic organic compounds such as plastic polymers, and a few natural ones, contain halogen atoms; these are known as halogenated compounds or organic halides. Chlorine is by far the most abundant of the halogens in seawater, and the only one needed in relatively large amounts (as chloride ions) by humans.
