Isotope

Atoms of the same element that have different numbers of neutrons in their nuclei, leading to different atomic masses but the same chemical behavior.

Neutrons

Tiny particles located within an atom's nucleus, possessing no electrical charge and having a mass that is marginally higher than protons.

  • Understand the organization of an atom, which consists of protons, neutrons, and electrons.
  • Acquire knowledge of the symbols and atomic numbers of typical elements.
  • Recognize the interplay between the atomic number (Z), mass number, and the variety of isotopes.
