- Inside the Atom
- Mass number (protons and neutrons) - top number.
- Atomic number (protons) - bottom number.
- Number of electrons in neutral atom = atomic number.
- Isotopes
- Atoms from the same element
- Same atomic number
- Different mass number (different number of neutrons).
- Knowing the relative isotopic masses [relative atomic mass for isotope] and relative abundance allows calculation of relative atomic mass.
