Concept explainers
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.
Equation for number of half lives passed:
