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
