One neutral atom of bromine has 35 protons, 35 electrons and 45 neutrons, according to ChemicalElements.com. Bromine has an atomic number of 35.Know More
Because an element's atomic number corresponds to the number of protons in one atom of the element, bromine must have 35 protons. A neutral atom must have the same number of protons and electrons, so bromine also has 35 electrons.
An easy way to determine the number of neutrons in an element is to subtract the number of protons in the element from the element's mass number. The mass number is obtained by rounding the atomic weight to the nearest whole number.
Bromine's atomic weight of 79.9 rounds to 80. Subtracting 35 protons from a mass number of 80 gives a result of 45.Learn more about Business Communications

Bromine will normally form one covalent bond. Bromine, which belongs to group 17 and period four of the Periodic Table, has seven outer shell or valence electrons. When a bromine atom forms a covalent bond with another bromine atom, the atom's outer shell has a full electron configuration.Full Answer >
Bromine has an atomic number of 35, which means it has 35 protons and 35 electrons. The two stable isotopes of bromine are Br-79 and Br-81, which contain 44 and 46 neutrons respectively. Bromine is a member of the halogen group and is designated with the chemical symbol "Br."Full Answer >
