Interpretation:

The option with correctly balanced equations is to be mentioned.

Concept introduction:

During positive beta decay, negative transmutation takes place and vice versa. During alpha decay, the loss of a helium takes place and both the atomic and mass number are decreased by 2 and 4 respectively.

Expert Solution & Answer

Answer to Problem 16STP

Correct answer: Option B is the correct option.

Explanation of Solution

Reason for correct option: In the first transmutation from thorium to radium atomic number decreased by 2 and mass number decreased by 4 indicating alpha decay. In the second transmutation from radium to actinium, the atomic number increased by one indicating negative beta decay followed by emission of electron. Both equations are displayed correctly in option B.

Conclusion

The other options have either one or both of the equations incorrect.
