Question

Assertion: The transmutation decay of ${}_{92}^{238}U$ can be shown as ${}_{92}^{238}U{\to }_{90}^{234}Th{+}_2^{4}He$.
Reason: The transmutation of ${}_{92}^{238}U$ is accompanied by the release of a beta particle.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
  
• C. Assertion is true but Reason is false
  
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

Answer: (C)

Assertion is true but Reason is false

${}_{92}^{238}U{\to }_{90}^{234}Th{+}_2^{4}He.$

The transmutation decay of ${}_{92}^{238}U$ is accompanied by the release of an $\alpha$ - particle.

$\therefore$ The, Assertion is true but reason is false no $\beta$ - particles emitted during decay.
