Describe the properties and uses of organohalogens. What is the trend in boiling points of halogens

There are ten chemical families: the alkali metals, alkali earth metals, transition metals, post-transition metals, metalloids, reactive nonmetals, halogens, ... They have oxidation numbers of ±4, -3, and -2. Halogens. The halogens are five non-metallic elements found in group 17 of the periodic table. All halogens ... Dimitri Mendeleev (1834- 1907) invented the first periodic table. He arranged the elements by their increasing atomic masses. Elements with similar properties ... Periodic Table; Halogens. Separation of Halogens from Liquids or Gases. The Group VIIA elements (fluorine, chlorine, bromine, iodine, astatine) are commonly ... Halogens (6) The Halogens are a generally nasty bunch. Think toxic choking fumes. But in compounds with the similarly strong-willed alkali earths, ... This volume is arranged into two sections: halogens and noble gases. Each one begins with an introduction to its family and is followed by chapters devoted to ... Other groups with specific names are the pnictogens (group 15), chalcogens (group 16), halogens (group 17), and the noble gases (group 18, also known as inert ... A family of nonmetallic, generally electronegative, elements that form group 17 (formerly group VIIa) of the periodic table. This group contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). Halogens have seven valence electrons and usually form anions with ... When halogens react with metals, they produce a wide range of salts, including calcium fluoride, sodium chloride (common table salt), silver bromide and ...
