A simply formula is the Atomic Mass of selenium (rounded to the whole number) - atomic number = neutrons. So Selenium 76 has 45 neutrons.
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
For each isotope of bohrium the number of neutrons is different. Number of neutrons = Mass number of an isotope of Bh – 107
