Group of elements when in ionic form may associate in salt formation.
Halogens is the reactive nonmetals that are in Group 17 of the periodic table (F, Cl, Br, I, and At). Compounds of these elements are called halogenides or halides.
The chemical elements either individually or collectively that constitute Group VIIA of the periodic table: namely, fluorine, chlorine, bromine iodine and astatine. Of these, only chlorine and bromine are used as disinfectant and sanitizers in pool and spas.
the column of elements from fluorine to astatine.
Reactive chemical elements with the ability to form one chemical bond in a molecule. Common halogens are fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).
A class of halide (i.e. containing Chlorine, Bromine or Iodine) compounds, including CFC's. These can break down to form various ozone-depleting radicals.
The halogens are the elements fluorine chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They are non-metals, and make up part of the 17 group in the periodic table. Compounds of these elements are called halogenides or halides. The halogens all have a strong unpleasant odor and will burn flesh. They do not dissolve well in water. The five elements are strongly electronegative. They are oxidizing agents, with fluorine being the strongest and astatine being the weakest. They react with most metals and many non-metals. Halogens form molecules which consists of atoms covalently bonded. With increasing atomic weight there is a gradation in physical properties. For example: Fluorine is a pale green gas of low density. Chlorine is a greenish-yellow gas 1.892 times as dense as fluorine. Bromine is a deep reddish-brown liquid which is three times as dense as water. Iodine is a grayish-black crystalline solid with a metallic appearance. And astatine is a solid with properties which indicate that it is somewhat metallic in character.
Substance containing fluorine, chlorine, bromine, and iodine.
chlorine and bromine are members of the halogen family of elements. As used, in swimming pools and spas, chlorine and bromine are referred to as halogen sanitizers. All other sanitizers are non-halogen.
Refers to any of five nonmetallic and electronegative chemical elements: astatine (At), bromine (Br), chlorine (Cl), fluorine (F), and iodine (I), such as those that may be found in refrigerants.
This important group of elements occupies Group VII of the periodic table. Its first element, fluorine, is the most strongly electronegative element known. All halogens are electron defficient and readily share electrons with other elements to staisfy their valency needs, eg. they all form compounds with hydrogen, with the formula HX (where =halogen)
Highly reactive elements that are harmful and often lethal to plants, animals and people in sufficient quantities.
The elements of Group 7 of the Periodic Table (i.e., fluorine, chlorine, bromine and iodine).
Elements from Group VII of the periodic table. Bromine, fluorine and chlorine are halogens. Of these, only fluorine is not important in ozone destruction, because it forms a stable compound, HF, in the stratosphere. halons Chemicals similar to CFCs, but containing bromine. Used for fire suppresion.
Any member of the family of very active elements consisting of fluorine, chlorine, bromine, and iodine. Chemically the hologens resemble one another closely and form a saline compound by simple combination with a metal.
These are the elements in group seven in the periodic table.
Group 7 of the periodic table of elements, with valence electron configurations of ns2np5. In contrast to the noble gases, the halogens are known for high levels of reactivity.
Group 7 of the periodic table of elements, including fluorine, chlorine, bromine, iodine, and astatine. The halogens are diatomic, and tend to form salts; hence their name, which comes from two Greek terms meaning "salt-forming."
The chemical elements either individually or collectively that constitute Group VIIB of the Periodic Table of Elements: fluorine, chlorine, bromine, iodine and astatine. Of these, only chlorine and bromine are used as disinfectants and sanitizers in pools and spas.
Group VIIA elements: F, Cl, Br, I
a family of chemical elements including fluorine, chlorine, bromine and iodine
The chemical elements in Group VIIB of the Periodic Table of Elements: fluorine, chlorine, bromine and iodine. Only chlorine and bromine are used as oxidisers, disinfectants and sanitisers in swimming pools.
Any of the group of poisonous non-metallic elements, fluorine, chlorine, bromine, iodine, and astatine, which form halides by simple union with a metal, as in sodium chloride.
A family group of elements, including bromine, chlorine, fluorine, astatine, and iodine, which are extremely active chemically. These elements exist in the free state normally as diatomic
A group of five elements – chlorine, bromine, iodine, fluorine and astatine – the first three of which are the active ingredients in virtually all sanitizer products.
Chemical substances found in many refrigerants containing chlorine, bromine, iodine, and fluorine.
