Bromine is the only nonmetallic liquid element. It is a heavy, mobile, reddish-brown liquid, volatilizing readily at room temperature to a red vapor with a strong disagreeable odor, resembling chlorine, and having a very irritating effect on the eyes and throat; it is readily soluble in water or carbon disulfide, forming a red solution, is less active than chlorine but more so than iodine.
It unites readily with many elements and has a bleaching action; when spilled on the skin it produces painful sores. It presents a serious health hazard, and maximum safety precautions should be taken when handling it.
Much of the bromine output in the U.S. was used in the production of ethylene dibromide, a lead scavenger used in making gasoline anti-knock compounds. Lead in gasoline, however, has been drastically reduced due to environmental considerations. This will greatly affect future production of bromine.
Bromine is used in making fumigants, flameproofing agents, water purification compounds, dyes, medicines, sanitizers, inorganic bromides for Photography,etc.
Organic bromides are also important.
Bromine is prepared by a method which comprises contacting hydrogen peroxide with an aqueous solution containing bromide ion and rapidly removing the bromine as it is formed. This method is particularly suitable for obtaining bromine from seawater, using the conventional intermediate, bromosulfuric solution.
The most common isotope of bromine is bromine-79 (Br-79), which makes up about 51% of naturally occurring bromine.
Bromine-79 has 44 neutrons and bromine-81 has 46 neutrons. All the isotopes of bromine has 35 protons.
The isotope 85Br has 35 protons and electrons; also 45 neutrons.
explanation about atomic mass of bromineIsotope Atomic mass Abundance(%) 79Br 78.91834 50.6981Br 80.91629 49.31therefore:Atomic mass of bromine element = 78.91834x0.5069+80.91629x0.4931= 79.904
4 different molecules can be formed from Br2 because this molecule has 2 possible isotopes (79Br and 81Br), so the combination of isotopes could include: 79Br with 79Br 81Br with 81Br 79Br with 81Br 81Br with 79Br
The number of neutrons in a bromine atom can vary depending on the isotope. The most common isotope of bromine, ^79Br, has 44 neutrons.
There are more bromine-79 atoms on Earth than bromine-80 atoms. Bromine-79 is the most abundant isotope of bromine, making up over 50% of natural bromine, while bromine-80 is a much rarer isotope.

The weighted average atomic mass of bromine is approximately 79.904 u. This average takes into account the abundance of each naturally occurring isotope of bromine, specifically bromine-79 (50.69%) and bromine-81 (49.31%).
All atoms of chemical elements contain protons, neutrons (excepting the isotope H-1)and electrons. The natural isotopes of bromine are 79Br and 81Br. For the list of all isotopes see the link below.
Bromine-35 refers to an isotope of bromine that has an atomic mass of 35 atomic mass units. It is one of the stable isotopes of bromine, with approximately 75% natural abundance. Isotopes of an element have the same number of protons but differing numbers of neutrons in their atomic nuclei.
The most common isotope of bromine is bromine-79 (Br-79), which makes up about 51% of naturally occurring bromine.
the 80 in Bromine-80 represents the rounded atomic mass (amu)
The isotope of bromine called 81-bromine. Since the element you are describing has 35 electrons, it must also have 35 protons. Therefore you end up with bromine which is the 35th element (since the amount of protons are equal to the elements number). Adding 46 to 35 gives you the weight of the specific bromine isotope, since the weight of the element is also the name of the isotope. It is also not radioactive.
Bromine 81 has 35 electrons, which is the same number of electrons as a neutral bromine atom since it is the most common isotope of bromine.
