Isotopes of an element

Isotopes of an element are atoms that have the same number of protons in their nuclei but differ in the number of neutrons.

Explanation:


  • Isotopes: Isotopes are different forms of an element that have the same number of protons in their nuclei but differ in the number of neutrons. This means that isotopes of an element have the same atomic number (number of protons) but different mass numbers.

  • Number of protons: Isotopes of an element have the same number of protons in their nuclei. The atomic number defines the identity of an element, so all isotopes of the same element have the same number of protons.

  • Number of neutrons: Isotopes of an element have different numbers of neutrons in their nuclei. This means that isotopes of the same element have different mass numbers. The mass number is the sum of the number of protons and neutrons in an atom.


Therefore, the correct answer is option D: Isotopes of an element have the same number of protons in their nuclei.
