THE “BOHR” MODEL OF THE   ATOM Niels Bohr (1885-1962), a Danish physicist, developed  the  quantum model  for the hydrogen atom.   He  proposed that the electrons in a hydrogen atom move  around the nucleus only in certain allowed circular  orbits (quantized orbits).  He calculated the radii for  these allowed orbits by using theories of classical  physics.  FIGURE 3 FIGURE 1 FIGURE 2

THE “WAVE MECHANICAL”   MODEL OF THE ATOM By the mid-1920’s it was apparent that the Bohr model  was incorrect.  Three young scientists, Louis Victor de  Broglie, Werner Heisenberg, and Werner Schrodinger,

Unformatted text preview: suggested that electrons have both particle and wave characteristics (such as photons of light). Mathematical analysis of this “quantum mechanical” model seemed to apply equally well to atoms other than just hydrogen – something Bohr’s model failed to do. In the Bohr model, the electron was assumed to move in circular orbits. In the wave mechanical model, on the other hand, the electron states are described by orbitals. Orbitals are nothing like orbits. FIGURE 4 FIGURE 5...
