Chapter 17, Problem 60E

Interpretation Introduction

Interpretation:

For the each given nuclide, nuclear equation showing alpha decay is to be written.

Concept introduction:

Alpha radiation is a consequence of emission of 2 protons as well as 2 neutrons from an unstable nucleus.

The helium nucleus is comprised two neutrons and two protons. Therefore, the symbol alpha particle is denoted as $\text{H}\text{e}$.

The alpha radiation can be represented by the nuclear reaction as follows:

$\underset{\text{parent nuclide}}{\underbracket{\text{U}}}\to \underset{\text{Daughter nuclides}}{\underbracket{\text{T}\text{h}+\text{H}\text{e}}}$
