Isotopes

  • Isotopes are forms of an element that have the same number of protons, but a different number of neutrons (and so different nucleon numbers).
  • Isotopes have the same properties as each other because they have the same number of electrons in their outer shell.

Nuclides

  • A nuclide is a type of isotope.
  • A nuclide refers to a specific nucleus that contains a certain number of protons and neutrons.
  • A carbon nuclide with 6 protons and 6 neutrons is different to a carbon nuclide with 6 protons and 7 neutrons. However, both are isotopes of carbon.
