Answer:
45 neutrons
Explanation:
Bromine has 35 protons and a mass number of 80. a) How many neutrons does the atom of bromine have? The mass number = protons + neutrons. Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
Electrons, protons, and neutrons are subatomic particles. In Bromine number of protons is 35, electrons are 35, and neutrons are 45.
What are subatomic particles?
Subatomic particles are the electrons, protons, and neutrons that are found in the atom. The number of electrons and protons is generally equal in the case of a neutral atom.
The atomic number of the Bromine atom is 35 and thus, protons are 35 and so are electrons.
The number of neutrons is given as the difference between the atomic mass and proton.
The number of neutrons are:
= Atomic mass - protons
= 80 - 35
= 45
The number of neutrons is 45, and the number of protons and electrons is 35.
