Question

Statement I : ${}^{12}C$ is an isotope of ${}^{14}C$.
Statement II: The nuclei of both atoms have the same number of neutrons.

• A. true, false
  
• B. false, true
  
• C. false, false
  
• D. true, true, correct explanation
  

Answer 1

The correct option is A true, false

${}^{12}C$ is an isotope of ${}^{14}C$.

As isotopes are variants of a particular chemical element that differ in neutron number but have the same number of protons.

${}^{12}C$ has $12-6=6$ neutrons.

${}^{14}$ has $14-6=8$ neutrons.

Hence, the statement $I$ is true but the statement $II$ is false.
