Atomic number 35 (from either Gr. βÏ?ωμος (brómos), meaning "stench"), occurs as chemical element in the periodic table that has the symbol Br & atomic number 35. The halogen element, bromine occurs as red volatile liquid at room temperature which has the reactivity between chlorine and iodine. This element is harmful to mortal tissue around the liquidity & its vapor irritates eyes & throat.

Notable characteristics
Atomic number 35 is the lone liquid nonmetal element at room temperature. These are the heavily, roving, reddish-'last liquid, that evaporates easy at standard temperature and pressures in a red vapor (its color resembles nitrogen dioxide) that has a heavy unsympathetic odor resembling that of chlorine. The halogen, br resembles cl chemically however is less active (these are other active than iodine however). Atomic number 35 is slightly soluble in water, and extremely soluble around carbon disulfide, aliphatic alcohols (such as methyl alcohol), & acetic acid. It bonds easily with several elements & has the hard bleaching action.

Atomic number 35 is extremely reactive & occurs as right oxidizing professional when in contact with fluids. It reacts smartly using amines, alkenes and phenols when well as aliphatic & aromatic hydrocarbons, ketones and acids (these are brominated by either addition or even substitution). By having numbers of of the metals & elements, anhydrous atomic number 35 is less reactive than soaked atomic number 35; yet, dry br reacts smartly by having aluminium, titanium, mercury as well as alkaline earth metals and alkaline metals.

Applications
Primary br is utilized to manufacture the wide kind of br compounds utilized within industry & agriculture. Traditionally a big apply of br was in the production of 1,2-Dibromoethane which in turn was utilized as a gasoline anti-knock agent for leaded gasolines prior to it were largely phased out due to environmental considerations.

Br is too utilized within making fumigants, flameproofing agencies, a water system filters compounds, dyes, medicinals, sanitizes, inorganic bromides for photography, etc. These are besides wont to form intermediates around organic synthesis, in which these are favorite to iodine due to its much moo cost.

Br is utilized to produce brominated vegetable oil, which is used as an emulsifier in many citrus-flavored soft drinks.

Aqueous br is orange & may be utilized around tests for alkenes and phenols. When added to an olefin it may lose its color when it reacts forming the colorless bromoalkane. When added to phenol the whiten precipitous (2,4,6-tribromophenol) will form.

History
Br was found by Antoine Balard at salt marshes of Montpellier in 1826 but was not produced around quantity until 1860. A French chemist & physicist Joseph-Louis Gay-Lussac suggested the title atomic number 35 due to the characteristic smell of the vapours.

Occurrence
Br occurs inside nature and severity when bromide salts within very diffused numbers in crustal rock. Due to leach bromide salts own accumulated within sea water (85 ppm), & can be economically recovered from either brine wells and a Dead Sea (up to 5000 ppm).

Close to 500 million kilograms ($350 million USD) of br come produced by a month (2001) worldwide by owning the United States and Israel being the primary producers. A big Br reserve in the United States is located in Columbia & Union County Arkansas.

Precautions
Elementary br occurs as hard thorn &, inside concentrated form, may develop painful bulla in contaminated skin and especially mucous membranes. Potentially moo concentrations of br vapor (from either Tenner ppm) may affect respiration, & inhalation of important numbers of atomic number 35 might seriously damage a respiratory technique.

Accordingly, a single should universally get into safety goggles and ensure adequate ventilation while treating br.

Recycling
Because of its high prices, atomic number 35 is ordinarily recycled rather than disposed of into the environment.
