Question

Chapter 25, Problem 19E

Interpretation Introduction

(a)

Interpretation:

From the given radioactive nucleus, the one with the largest value for decay constant needs to be determined.

Concept introduction:

Chemical decay is also known as chemical decomposition. It is the process of breaking down of two or more fragments of a single entity. If there is a decrease in rate proportional to its current value, it is subjected to exponential decay. This is given by λ.

Interpretation Introduction

(b)

Interpretation:

From the given radioactive nucleus, the one which loses 75% of its radioactivity in one month needs to be determined.

Concept introduction:

The process of decay by which an unstable nucleus loses its energy by emitting radiation is called radioactive decay.

The particles emitted in this process are alpha and beta particles.

They produce gamma rays or electrons in cases of internal conversion.

Interpretation Introduction

(c)

Interpretation:

The element that loses 99% of its radioactivity in one month needs to be determined.

Concept introduction:

Chemical decay is also known as chemical decomposition. It is the process of breaking down of two or more fragments of a single entity.

The process of decay by which an unstable nucleus loses its energy by emitting radiation is called radioactive decay.
