Assertion : For maximum stability N/P ratio must be equal to 1 Reason : Loss of alpha - beta - particles has no role in N/P ratio

Answer»

If both assertion and reason are true and the reason is the correct explanation of the assertion
If both assertion and reason are true but reason is not the correct EXPLANANTION of the assertion
If assertion is true but reason is false
If the assertion and reason both are false

Solution :Loss of `ALPHA or beta-`particle is to change N/P ratio so that it lies with the in the stability belt. Loss of `alpha-`particles INCREASES N/P ratio while loss of `beta-` particle DECREASES N/P ratio
