Periodic Table as Formulated by Mendeleev in 1871
eka-B Sc 1879
eka-Si Ge 1886

Elements placed according to the value of their
atomic weights present a clear periodicity of
properties. (Mendeleev, 1869)

The Quantum Mechanics Basis of the Periodic Table
  • 1926, 1927 Schrodinger and Heisenberg describe
    the wave properties of the electron
  • Electrons are treated as waves and can be
    described by a mathematical function ?.
  • Using this function ?, the probability to find
    the electron in a given place in space can be
    calculated.
  • The area of space where the electron is most
    likely located is called orbital.
  • Schrodinger formulated a differential equation
    that can be used to determine the wave function
    of the electron
  • H ? E ?
  • H is a Hamiltonian operator or in short
    Hamiltonian.
  • A Hamiltonian is a function that has as argument
    another function.
