Amiya Odonnell · Answer 1

I believe the correct answer is C. The number of neutrons in the 253/100 Fm would be 153. The numbers beside Fm are used to determine this. Two hundred fifty three represents the mass number which is the sum of protons and neutrons in the nuclide while 100 represents the atomic number which is the number of protons. Therefore,

253 = neutrons + 100

neutrons = 153
