As per your syllabus, which pair of nuclides represents ISOBARS (same A, different Z)?
A¹²C and ¹⁴C
B¹⁴₆C and ¹⁴₇N
C³⁵Cl and ³⁷Cl
D¹H and ²H
Answer & Solution
Correct answer: B. ¹⁴₆C and ¹⁴₇N
As per your syllabus, isobars share mass number but differ in atomic number — ¹⁴C and ¹⁴N (both A = 14, Z = 6 vs 7).
