Isotope Relationships

  • Element A (11 protons, 11 neutrons) and Element B (11 protons, 12 neutrons) are isotopes.
  • Elements C (13 protons, 13 electrons) and D (12 protons, 13 electrons) are not isotopes due to differing proton numbers.

Unstable Isotopes

  • Unstable isotopes, known as radioisotopes, emit radiation during decay.
  • They decay by emitting particles such as alpha particles, beta particles, positrons, and gamma rays.
  • They possess an imbalance of neutrons and protons.

  • Polonium-210 is a radioactive isotope that emits alpha particles; its atomic number is 84.
  • It was discovered by Marie and Pierre Curie, named after Poland.
  • Polonium-210 has 126 neutrons.

General Concepts

  • Each element has a unique number of protons, which identifies the element.
  • Isotopes of an element have identical proton counts and different neutron counts.
  • Changes in neutron numbers lead to different isotopes of the same element.
