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.
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.

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.
