In chemistry, a halide (rarely halogenide [1]) is a binary chemical compound, of which one part is a halogen atom and the other part is an element or radical that is less electronegative (or more electropositive) than the halogen, to make a fluoride, chloride, bromide, iodide, astatide, or theoretically tennesside compound.
Halides are compounds containing halogens. The halogens may either be bonded to another element through covalent bonding or (as in many metal halides) present in the form of the halide ion . Subcategories
The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...
Metal halides are compounds between metals and halogens. Some, such as sodium chloride are ionic , while others are covalently bonded . A few metal halides are discrete molecules, such as uranium hexafluoride , but most adopt polymeric structures, such as palladium chloride .
Examples of non-symmetrical pseudohalogen compounds (pseudohalogen halides Ps−X, where Ps is a pseudohalogen and X is a halogen, or interpseudohalogens Ps 1 −Ps 2, where Ps 1 and Ps 2 are two different pseudohalogens), analogous to the binary interhalogen compounds, are cyanogen halides like cyanogen chloride (Cl−CN), cyanogen bromide (Br ...
Alkali metal halides, or alkali halides, are the family of inorganic compounds with the chemical formula MX, where M is an alkali metal and X is a halogen. These compounds are the often commercially significant sources of these metals and halides. The best known of these compounds is sodium chloride, table salt. [1]
Metal halides are compounds between metals and halogens. Some, such as sodium chloride are ionic , while others such as uranium hexafluoride have considerable covalent character to their bonding. This category serves as a complement to Category:Nonmetal halides
Oxohalides can be seen as compounds intermediate between oxides and halides. There are three general methods of synthesis: [1] Partial oxidation of a halide: 2 PCl 3 + O 2 → 2 POCl 3. In this example, the oxidation state increases by two and the electrical charge is unchanged. Partial halogenation of an oxide: 2 V 2 O 5 + 6 Cl 2 + 3 C → 4 ...
