How many neutrons are in bromine 79?
44 neutrons
Bromine has an atomic number of 35, and so has 35 protons. You are told that the mass number is 79, and so there are a total of 79 protons plus neutrons. Therefore there must be (79 – 35) neutrons = 44 neutrons.
What isotope has 16 protons 18 electrons 16 neutrons?
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 18 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
How many neutrons are in bromine?
Bromine has a mass number of 80 and 35 protons so 80-35 = 45 neutrons.
