Answer
a) 48
b) 44
c) 114
d) 110
Work Step by Step
To find the number of neutrons for a particular isotope of an atom, you must subtract the atomic number from the atomic mass:
a) Atomic Number: 36, Atomic Mass: 84
Neutrons: 84 - 36 = 48
b) Atomic Number: 35, Atomic Mass: 79
Neutrons: 79 - 35 = 44
c) Atomic Number: 76, Atomic Mass: 190
Neutrons: 190 - 76 = 114
d) Atomic Number: 75, Atomic Mass: 185
Neutrons: 185 - 75 = 110
