Chapter 21, Problem 25E

Interpretation Introduction

Interpretation: The best suitable statement related to the alpha and proton emission from the given statements is to be identified.

Concept introduction: Nuclei containing proton number $2$ , $$ , $20$

$28$ , $50$ ,or $82$ or neutron number $2$ , $8$ , $20$

$28$ , $50$ ,or $82$ are more stable than the nuclei that do not contain these number of nucleons.

The nuclides that contain even number of proton and neutrons are more stable.

To determine: The statement that best explains that why alpha emission is relatively common, but proton emission is extremely rare.
