Question

Assertion: Nitrogen undergoes radioactive disintegration upon bombarding with a neutron.

Reason: ${}_7{N}^{14}+{}_0{n}^1\to {}_6{C}^{14}+{}_1{H}^1$.

• 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

The correct option is A Both Assertion and Reason are true and Reason is the correct explanation of Assertion

The nuclear reaction ${}_7{N}^{14}+{}_0{n}^1\to {}_6{C}^{14}+{}_1{H}^1$. is correct.
For reactants, the sum of the atomic numbers is $7+0=7$.
For products, the sum of the atomic numbers is $6+1=7$.
For reactants, the sum of the mass numbers is $14+1=15$.
For products, the sum of the mass numbers is $14+1=15$.
