When describing the isotopes of the same element, the most accurate statement is that they have:

Correct answer: C. the same atomic number but different atomic masses

  • A. the same spin
  • B. the same atomic mass but different atomic numbers
  • C. the same atomic number but different atomic masses
  • D. the same chemical properties and therefore can not be separated
  • E. a coexistence limit, that is, no element can have more than three isotopes

Explanation

Those elements that have the same atomic number but a different mass number are referred to as isotopes.

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.
