Radioactive nuclei emit beta^-1 particle...

Radioactive nuclei emit `beta^-1` particles.
Electrons exist inside the nucleus.

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason are true but Reason is not correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
C
( C) the `beta^(-)` particle ( e) emitted from the nucleus in same radioactive trancformation . So electrons do not exisrt in the abverage life transformation

    A radioactive sample emits n beta -particles in 2 sec. In next 2 sec it emits 0.75 n beta - particles, what is the mean life of the sample ?

    Explain how radio-active nucleus can emit beta -particles even though nuclei do not contain these particles. Hence explain why the mass number of radioactive nuclide does not change during beta - decay.

    Some radioactive nucleus may emit

    Assertion (A) : Nucleus of the atom does not contain electrons, yet it emits beta- particles in the form of electrons. Reason (R): In the nucleus , protons and neutrons exchange mesons frequently.

    Some radioactive nucleus may emit.
