Question
Chapter 10.5, Problem 10.16P
Interpretation Introduction
Interpretation:
The fraction of thallium-201 should be calculated which is still present in an individual after 9 days.
Concept Introduction:
The time which is required for a quantity to reduce to half of its initial value is known as half -life.
Or,
The time at which the reactant concentration is reduced to half of its initial concentration is known as half-life.
The expression for calculating amount left after decay of radioactive atom is shown as:
Where, t = number of half-lives that passed.
