Which of the following pair of nuclides are Isobars?
- A \({ }_1^2 H ,{ }_1^3 H\)
- B \({ }_1^3 H ,{ }_2^3 He\)
- C \({ }_{80}^{198} Hg ,{ }_{79}^{197} Au\)
- D \({ }_1^1 H ,{ }_1^3 H\)
Answer & Solution
Correct Answer
(B) \({ }_1^3 H ,{ }_2^3 He\)
Step-by-step Solution
Detailed explanation
Isobars are nuclides that have the same mass number \(( A )\) but different atomic numbers (Z). In this pair, both have a mass number of 3, while their atomic numbers are 1 and 2. B) \({ }_1^3 H ,{ }_2^3 He\).
