Question

Assertion :When there is emission of $\beta$-particle atomic increases by one unit.
${}_6^{14}C⟶{}_7^{14}N+{}_{-1}^{0}e$ Reason: Neutron is converted to proton
${}_o^{1}n⟶{}_1^{1}p+{}_{-1}^{o}e$

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

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

When there is an emission of $\beta$-particle atomic number increases by one unit and atomic mass remains unchanged.

${}_6^{14}C⟶{}_7^{14}N+{}_{-1}^{0}e$

Neutron is converted to proton due to which the number of protons increases by 1 and the number of neutrons decreases by 1 unit.

${}_o^{1}n⟶{}_1^{1}p+{}_{-1}^{o}e$

Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
