# How many neutrons does an element have if its atomic number is 50 and its mass number is 166 # of neutrons = mass number - # of protons.
# of protons = atomic number

therefore,
166-50 = 116 neutrons 105. the atomic mass of an atom are the protons + neutrons. the atomic number of an atom is the number of protons. so, to find the neutrons, subtract 153 - 48 to get 105. 95 neutrons hope this helps 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.

protons+neutrons=atomic mass.

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.

150=43+x

150-43=x

107=x Number of neutrons = atomic mass - atomic number

Number of neutrons = (150) - (47)

Number of neutrons = 103 Number of nuetrons=atomic mass- atomic number

= 154-52

=102 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

Hope this helps! The Element would have 197 neutrons  ### Other questions on the subject: Chemistry Chemistry, 21.06.2019 17:10, shafferakr6
