bromine, Nonmetallic chemical element, chemical symbol Br, atomic number 35.One of the halogens, it is a deep red, fuming liquid at ordinary temperatures (freezing point 19 °F [−7.2 °C]; boiling point 138 °F [59 °C]) that contains diatomic molecules (Br 2), and it does not occur free in nature.It is obtained from seawater and brines or salt beds.
Physical Properties of Halogens. As elements, chlorine and fluorine are gases at room temperature, bromine is a dark orange liquid, and iodine is a dark purple-gray solid. Astatine is so rare that its properties are mostly unknown. In the picture below we see chlorine gas on the left (green), bromine solid and vapor in the middle (orange), and ...
There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine. These elements can exist in pure form in other arrangements. For example, oxygen can exist as the triatomic molecule, ozone. This is a list of the seven diatomic elements. The seven diatomic elements are: Hydrogen (H 2) Nitrogen (N 2) …

The reddish-brown liquid of bromine found in nature is a combination of two stable isotopes: bromine-79 (50.54 percent) and bromine-81 (49.46 percent). With the periodic table symbol Br, atomic number 35, and electron configuration [ Ar ] 3d 10 4s 2 4p 5, bromine reaches its boiling point at 58.78°C, while the melting point is achieved at …
Overview Bromine is a member of the halogen family. Halogens are the elements that make up Group 17 (VIIA) of the periodic table. The periodic table is a chart that shows how elements are related to one another. The …
Bromine is found naturally in the earth's crust and in seawater in various chemical forms. Bromine can also be found as an alternative to chlorine in swimming …
June 5, 2014 at 1:09 pm. Bromine is a secret ingredient in the recipe for animal life. The element is necessary for helping cells in multicellular animals stick together, researchers report in the ...
Bromine - Bromine has an atomic number of 35 with a symbol of Br. It was first discovered in 1826. In its elemental form, it is the diatomic molecule Br 2. At room temperature, bromine is a reddish- brown liquid. Its oxidation states vary from -1, +1, 3, 4 and 5. Bromine is more reactive than iodine, but not as reactive as chlorine.
The experiments of different potential active bromine species with substrate For H 2 O + Br 2 species, Br 2 molecule (0.5 M, 256 µL) was added into 10 mL H 2 O and the mixture solution was ...
The bromine molecule, Br2, is known to contain two atoms of bromine. A mass spectrum of the moluecular ions formed showned three Br2+ peaks, with mass numbers 158, 160, and 162. Use this information to determine which isotopes of bromine occur in nature.
Biological half-lives of bromine in 15 different organs and tissues of the rat, in addition to the whole-body half-life, were determined by measuring the radioactive concentration of 82Br-bromide in samples of tissues collected at the time intervals of 12-396 hr from animals that continuously (up to 17 d) received 82Br-labeled bromide in their drinking water.
