Question
Chapter 6, Problem 1VSC
To determine

The most radioactive element among.

Uranium 235

Potassium 40

  1. Both are equally radioactive

Expert Solution & Answer
Check Mark

Answer to Problem 1VSC

Solution:

The most radioactive element is uranium 235 .

Explanation of Solution

Introduction:

Radioactive elements emit radiation and decays by themselves.

The half-life of radioactive substance is the time taken by a substance to decay half of its original value. A radioactive isotope with lower half-life decays fast as compared to another radioactive isotopes.

The given plot shows that uranium 235 has half-life of less than 1 unit and potassium 40 has a half-life of 1.25 units.

So, the most radioactive element is uranium 235 correct answer is (a)

Conclusion:

The most radioactive element is uranium 235 .
