# of protons = atomic number
166-50 = 116 neutrons
To find the neutrons of an element, you simply have to subtract the mass number and atomic number. 156 - 40 is 116.
atomic number = protons.
170 (mass) - 41 (proton/number) = 129
that should be ur answer. I hope this helps!
It would be 107 neutrons as mass number is atomic number (protons) and neutrons added together.
Number of neutrons = atomic mass - atomic number
Number of neutrons = (150) - (47)
Number of neutrons = 103
Number of nuetrons=atomic mass- atomic number
Ok so I think you would first subtract
156 - 50 = 106
Since atomic number is based on the number of protons, you should subtract the 50 from 156
106 should be your answer
Hope this helps!
The Element would have 197 neutrons
