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.
In underground salt beds, and in a lot of medicine
Bromine is made by introducing Chlorine into an aqueous solution of
bromide, that is a salt composed of a metal and bromine
It may be Bromine-79 (79Br) because it is one of the 2 stable isotopes. The other one is Bromine-81 (81Br).
The isotope 85Br has 35 protons and electrons; also 45 neutrons.
For young students, let's assume that all elements of bromine have a molecular weight of 80. Because electrons have effectively no mass, what the molecular weight is is basically the number of protons plus the number of neutrons. So the number of neutrons = 80 - 35 = 45.For older students, bromine has two isotopes, 79Br and 81Br. So, for the former isotope bromine would have 44 neutrons, and for the latter isotope it would have 46 neutrons. The natural abundance of each isotope is approx 50%.Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.
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
The chemical symbol of bromine is Br
It is the 35th isotope of Bromine
Bromine is a chemical element and has several isotopes.
Bromine is a chemical element and has several isotopes.

Bromine's average eight is 79.904 is the answer in my reference, with more than 20 isotopes.
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.
This is the radioactive isotope bromine-78.
It may be Bromine-79 (79Br) because it is one of the 2 stable isotopes. The other one is Bromine-81 (81Br).
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.
This occurs because bromine has stable isotopes of mass 79 and 81. There is a slight natural excess of the lighter isotope, so that the average is 79.9.
About 33 hours
The isotope 85Br has 35 protons and electrons; also 45 neutrons.
