Chapter 25.4, Problem 1RC
Interpretation Introduction

INTERPRETATION:

The percentage of thorium decomposed after the given period of time should be determined using the concepts of half life.

CONCEPT INTRODUCTION:

Radioactive decay:

A nucleus undergoes disintegration in-order to become stable by emitting radiations such as alpha, beta and gamma particles.

Radioactive series:

The series in which successive disintegration of unstable nuclei is formed until a stable nucleus is formed.

Half life:

The time used for the decay of the half of the radioactive isotope to undergo decay.

Halflife,t12=0.693λwhereλisthedecayconstant

(12)numberofhalflives=decimalamountremaining

Equation for number of half lives passed:

No.ofhalflives=TotaltimeHalflife
