Question

In a radioactive decay chain, T90232h nucleus decays to P82212b  nucleus. Let Nα and Nβ be the number of α and -β particles, respectively, emitted in this decay process. Which of the following statements is (are) true ?

Options

A.

Nα=5

B.

Nα=6

C.

Nβ=2

D.

Nβ=4

Solution

T90232h is converting into P82212b
Change in mass number (A) = 20
∴no of α particle =204=5
Due to 5 α particle, z will change by 10 unit.
Since given change is 8, therefore no. of β particle is 2
