_ are such nuclei of an element that have the same mass number A, but have different charge number Z.
Correct answer: B. Isobars
- A. Isotopes
- B. Isobars
- C. Isomers
- D. Isotherms
Explanation
Isobars are nuclei that have the same mass number (A), but a different atomic number (Z). Isobars should not be confused with isotopes, which share the same atomic number, and therefore belong to the same chemical element, but have varying mass numbers. Isomers are two or more nuclides that consist of the same no. of protons and the same no. of neutrons but have different energy and manner of radioactive decay, and that exist for a measurable interval of time. Hence, option B is correct.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
