• What is an isotope?

  Atoms with the same number of protons but different numbers of neutrons.
• What is relative isotopes mass?

  The mass of one atom of an isotope compared to one twelfth of the mass of one atom of carbon-12.
• Do isotopes have similiar chemical properties?

  Yes they have similar chemical properties because they have the same electronic structure.
• Do isotopes have similiar physical properties?

  They might have slightly varying physical properties due to their different masses.
• What is relative molecular mass?

  The average mass of a molecule compared to one twelfth of the mass of one atom of carbon-12.
