Question

Statement: parent element of `(4n + 1)` series is Plutonim `-241`
Explanation: It decays to give `8alpha` and `5beta` particles.
A. `S` is correct but `E` is wrong.
B. `S` is wrong but `E` is correct.
C. Both `S` and `E` are correct and `E` is correct explanation of `S`.
D. Both `S` and `E` are correct but `E` is not correct explanation of `S`.

Answer 1

Correct Answer - `c`
parent element of `(4n + 1)` series is `.^(241)Pu`. The series gives `8alpha` and `5beta-` particlles to give finally stable element `.^(209)Bi`.
