Question
Determine the number of neutrons and protons in (a) $_{90 }^{232} \mathrm{Th}$(b) $_{82 }^{211} \mathrm{Pb},$ and(c) $^{60}_{27} \mathrm{Co}$
Step 1
The mass number (A) of an atom is the sum of the number of protons and neutrons in the nucleus. Therefore, the number of neutrons (N) can be calculated by subtracting the atomic number from the mass number (N = A - Z). Show more…
