Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
The chemical name for BrO2 is bromine dioxide. Be careful though - bromite, which is different, is the name for the chemical BrO2-.
The chemical formula for bromine silicide is BrSi.
The chemical formula for bromine trichloride is BrCl3.
The chemical formula for cesium is Cs and the chemical formula for bromine is Br.
Bromine is a chemical element and has several isotopes.
Bromine is a chemical element and has several isotopes.
A chemical element is homogeneous, if we do not take into account isotopes.
Like almost all of the other elements bromine is a mixture of so-called isotopes. All of these isotopes are bromine and have almost identical chemical properties. They all have the same number of protons in the nuclei of their atoms. However, the numbers of neutrons in their nuclei vary. The atoms of some isotopes of bromine are a little heavier than the atoms of other isotopes. The atomic weight of bromine is the average weight of all of the isotopes of bromine, so it cannot be a whole number.
Two natural isotopes of bromine are known:- bromine-79: 50,69 %- 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.
Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
Bromine is the member of group 7 that exists as two stable isotopes: bromine-79 and bromine-81. These isotopes have slightly different atomic masses due to variations in the number of neutrons.
Bromine has two stable isotopes, bromine-79 and bromine-81, which are the only two isotopes that occur naturally. This limited natural isotopic composition is unusual compared to other elements that have a wider range of stable isotopes.
81Br is one of the stable isotopes of bromine.
Normally, bromine forms an anion, because it gains one electron to have a full octet, and is then negative. (Br1-) However, bromine can from a cation, as is the case when using N-bromosuccinimide (Br+ is given off).
the chemical symbol is Br :)
