How many protons neutrons and electrons are there in a bromine atom?

The Bromine atom contains: 35 protons, 35 electrons, and 45 neutrons.


How many protons electrons and neutrons in bromine-80?

79? I'm pretty sure the atomic mass of Bromine is 80. Incase you were wrong, the Atomic mass = Number of protons + Neutrons, which is 80. The atomic number is 35, which is the number of protons. Protons = 35. So the No. of Neutrons = 80 ( protons & neutrons) - 35 (protons) = 45 ( No. of neutrons) and Finally for electrons = the number of protons which is 35.


How many electrons protons and neutrons are there in an atom of bromine 81?

An atom of bromine-81 has 35 protons, 35 electrons, and 46 neutrons. This is because the atomic number of bromine is 35, which corresponds to the number of protons and electrons, and the atomic mass of bromine-81 is 81, which is the sum of protons and neutrons.
