    Edme Mariotte

    In collaboration with Robert Boyle, they established a law by which pressure and volume are inversely related.

    Robert Boyle

    In collaboration with Edme Mariotte, they established a law by which pressure and volume are inversely related.
  • Period: to

    Jacques Alexander César Charles

    He made a law by which volume and temperature are directly related.
  • Period: to

    John Dalton

    He proposed that all mater is made out of atoms and that atoms cannot be broken into smaller particles.
  • Period: to

    Lorenzo Romano Amedeo Carlo Avogadro

    He made a law by which volume and number of moles are directly related.
  • Period: to

    Louis Joseph Gay-Lussac

    He made a law by which pressure and temperature are directly related.
  • Period: to

    François-Marie Raoult

    He established a law by which the vapour pressure of a solution is equal to the product of the vapour pressure of the pure solvent multiplied by the molar fraction of the solvent.
  • Period: to

    James Clerk Maxwell

    In collaboration with Ludwig Boltzmann, they defined the Maxwell-Boltzmann distribution that explains that at a certain temperature which is below the boiling point and above the freezing point. Most molecules have a medium/low kinetic energy but a small percentage will always have a high kinetic energy.
  • Period: to

    Ludwig Eduard Boltzmann

    In collaboration with James Clerk Maxwell, they defined the Maxwell-Boltzmann distribution that explains that at a certain temperature which is below the boiling point and above the freezing point. Most molecules have a medium/low kinetic energy but a small percentage will always have a high kinetic energy.
  • Period: to

    Joseph John Thomson

    He came up with the “plum pudding” model for the atom. He thought atoms were a positively charged sphere with electrons inside of it
  • Period: to

    Ernest Rutherford

    Except for two errors his model was very accurate. He proposed atoms must be mostly empty space with a very little and dense positive nucleus in the middle.
  • Period: to

    Niels Henrik David Bohr

    He used the information of the emission and absorption spectra to suggest a more accurate model of the atom.
  • Period: to

    Ernest Rudolf Josef Alexander Schrödinger

    To include this principle in atomic orbital theory we used his equation to predict areas where probably would be the electrons.
  • Period: to

    Louis de Broglie

    He suggested the wave-particle duality of electrons.
  • Period: to

    Friedrich Hermann Hund

    He created Hund’s rule by which for orbitals with an equal amount of energy we must place one electron in each before adding a second electron.
  • Period: to

    Wolfgang Ernst Pauli

    He created the Pauli Exclusion Principle by which you have to draw electrons in the same orbital with opposite signs.
  • Period: to

    Werner Karl Heisenberg

    He came up with the uncertainty principle by which we cannot know both the position and the momentum of an electron at the same time.
