Two  atoms that  are isotopes of  one another that   must the same number of   protons ( answer B)

Explanation

  • Isotope  are two or more forms  of the same element that contain  the same  number of protons and  electron   but different  number  of neutrons.
  • For example  carbon 12  and carbon 14   are both  isotope of carbon.
  • Carbon 12 has 12 neutrons while  carbon 14 has  8 neutrons.

Answer:

Two atoms that are isotopes of one another must have the same number of Protons.

Explanation:

An isotope is a different form of the same atoms having the same atomic number but differ in atomic mass.

This difference in atomic mass occurs due to the presence of extra nuetrons in atoms.

Example: Isotopes of hydrogen protium, deuterium, and tritium.

Protium nucleus does not contain any neutrons while deuterium has 1 and tritium has 2 neutrons.
