Chapter 21, Problem 21.38QP

Interpretation Introduction

Interpretation:

Suitable isotope should be identify which show nuclear fission.

Concept introduction:

Nuclear fission:

It is the process in which a heavy nucleolus (whose mass number greater than the 200) splits into form smaller nuclei of intermediate mass and one more neutrons.

Example:

The nuclear fission for uranium is as follows:

${}_{\text{92}}{\text{U}}^{\text{235}}{\text{+0n}}^{\text{1}}\stackrel{}{\to }{\text{3n}}_{\text{0}}^{\text{1}}{\text{+Kr}}_{\text{36}}^{\text{92}}{\text{+Ba}}_{\text{56}}^{\text{141}}\text{+Energy}$

Plutonium -239(${\text{Pu}}^{239}$): This isotope of plutonium is the primary fissile isotope used for the production of nuclear weapons.

Uranium -235(${\text{U}}^{235}$): This isotope of uranium is the primary fissile isotope used for the production of nuclear weapons& vast use in fission reaction
