Assertion : ₁₁²² Mg emits a positron giving 22 12 Mg . Reason : In ⁺ emission neutron is transformed into proton.

Options

  1. AIf both assertion and reason are true and the reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true and the reason is not the correct explanation of the assertion
  3. CIf assertion is true but reason is false
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

₁₁ Na ²² ₁₂ Mg ²²+ _ -1 ^0 It involves -particle emission. While positron emission is due to the conversion of proton into neutron. ₁^1 p ₀^1 n+ ₁^0
