Br-80 has 35 protons.
From the Periodic Table of the elements, bromine, Br, has the atomic number 35. By definition, this means that bromine atoms have 35 protons in their nuclei.
Bromine has 35 protons, 35 electrons, and 45 neutrons.
Bromine have 35 protons, 35 electrons and 44 (for Br-79) or 46 (for Br-81) neutrons.

Br-80 has 35 protons.
Br has an atomic number of 35 giving it 35 protons. Since it has a charge of 1- it will have 36 electrons to form a octet.Br- will have 35 protons and 36 electrons. The negative charge indicates it gained an electron.
The nucleus is where all the mass of the atom is to be found and every nucleus is made of Protons and Neutrons which have about the same mass. Together these therefore give the atom its Mass Number. Thus if you know the Mass Number you know how many Protons and Neutrons the atom contains. If you are then told how many Neutrons there are, a simple subtraction of this number from the Mass Number will give you the number of Protons. The number of Protons in an atom defines what is called its "Atomic Number" and this is unique to each element. You can then look up the Atomic Number in a Periodic Table of the Elements and find out which element has that number.

The element boron has atomic number 5; therefore, there are 5 protons in each boron atom, because the atomic number of an element is defined as the number of protons in each atom of an element.
Br-80 has 35 protons.
The symbol of Bromine is Br and number of protons(or atomic number) which is also equal to the number of electrons is 35
The number 35 above Br represents its atomic number. It is also equal to number of protons in Bromine.
Number of Protons: 35 Number of Neutrons:45 Number of Electrons:35
