Chapter 2: Problem 12

Calculate the number of neutrons of \({ }^{239} \mathrm{Pu}\).

Short Answer

Expert verified
The number of neutrons in the \({ }^{239} \mathrm{Pu}\) is 145.

Step by step solution

01

Determination of Number of Protons and Nucleons

Identify the atomic number of plutonium, which is 94. This is the number of protons present in the plutonium atom. The given superscript, here 239, represents the total number of protons and neutrons combined, which is also known as the mass number.
02

Calculation of Number of Neutrons

Subtract the number of protons from the mass number to find the number of neutrons. So, in this case, subtract 94 protons from the total nucleons, 239. This will give the number of neutrons in the isotope.
