Species of the same element that have the same atomic number "Z" but have different mass number "A" are called _ of that element.
Correct answer: B. Isotopes
- A. Radioactive rays
- B. Isotopes
- C. Alpha particles
- D. Beta particles
Explanation
Isotopes of the same element will have the same atomic number but different mass numbers.

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.
