STPM Chemistry: Atoms, Molecules and Stoichiometry [Checklist]

  • Electron: A subatomic particle that has a very low mass and carries a single negative electric charge.
  • Neutron: A subatomic particle that bears no net electric charge. Its mass is slightly greater than a proton’s.
  • Proton: A subatomic particle having a single positive electric charge. The mass of a proton is about 1840 times that of an electron.
  • Nucleus: The central core of an atom.
  • Nucleon number (mass number) Symbol A: The total number of protons and neutrons found in the nucleus of an atom.
  • Avogadro’s number (NA): 6.02 X 1023; the number of particles in a mole.
  • Relative atomic mass, Ar, is defined as the mass of one atom of an element relative to 1/12 of the mass of an atom of carbon-12, which has a mass of 12.00 atomic mass units.
  • Relative isotopic mass is like relative atomic mass in that it deals with atoms. The difference is that we are dealing with different forms of the same element.
  • Isotopes have the same number of protons, but different numbers of neutrons. Hence, isotopes of an element have different masses.
  • Relative molecular mass, Mr, is defined as the mass of one molecule of an element or compound relative to 1/12 of the mass of an atom of carbon-12, which has a mass of 12.00 atomic mass units.
  • Relative formula mass is used for substances that do not contain molecules, such as sodium chloride, NaCl, and is the sum of all the relative atomic masses of the atoms present in the formula of the substance.
  • It is important to remember that since these are all relative masses, they have no units.
  • Mole: The amount of substance which contains 6 × 1023 atoms, ions or molecules. This number is called
  • Avogadro’s constant.
  • Empirical formula: A formula showing the simplest ratio of atoms present.
  • Molecular formula: A formula showing the actual number of atoms of each element present in one molecule.
