Question

Verified by Toppr

Answer 1

$_{90}^{232}$ Th has converted into $_{82}^{212} P b$

Change in mass number (A) = $20$

$∴$ no of $α$ particle $= \frac{2 0}{4} = 5$

Due to $5 α$ particle, z will change by $10$ unit.

Since given change is $8$ , therefore no. of the beta particle is $10 - 8 = 2$

Answer 2

$_{90}^{232}$ Th has converted into $_{82}^{212} P b$

Change in mass number (A) = $20$

$∴$ no of $α$ particle $= \frac{2 0}{4} = 5$

Due to $5 α$ particle, z will change by $10$ unit.

Since given change is $8$ , therefore no. of the beta particle is $10 - 8 = 2$

In a radioactive decay chain, 90232​Th nucleus decays to 82212​Pb 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?

Nα​=5

Nα​=6

Nβ​=2

Nβ​=4

90232​Th has converted into 82212​Pb Change in mass number (A) = 20 ∴ no of α particle =420​=5 Due to 5α particle, z will change by 10 unit. Since given change is 8, therefore no. of the beta particle is 10−8=2
