Answer

a) 45 neutrons b) 16 neutrons c) 61 neutrons d) 125 neutrons

Work Step by Step

The formula for neutrons is Neutrons = Mass - Atomic number a) given mass= 80 and Atomic number = 35 we substitute it into the equation and find the neutrons. Neutrons = Mass - Atomic number Neutrons = 80 - 35 Neutrons = 45 neutrons b) given mass= 32 and Atomic number = 16 we substitute it into the equation and find the neutrons. Neutrons = Mass - Atomic number Neutrons = 32 - 16 Neutrons = 16 neutrons c) given mass= 108 and Atomic number = 47 we substitute it into the equation and find the neutrons. Neutrons = Mass - Atomic number Neutrons = 108 - 47 Neutrons = 61 neutrons d) given mass= 207 and Atomic number = 82 we substitute it into the equation and find the neutrons. Neutrons = Mass - Atomic number Neutrons = 207 - 82 Neutrons = 125 neutrons
