26.2 Borhr Model of the Atom and Atomic Spectra
Bohr Model of the Atom and Atomic Spectra
Bohr Model of the Atom
• Electrons move in circular orbits about the nucleus.
• Only orbits of certain radii/energy are possible.
En = -2.18×10−18 J / n2 = -13.6eV / n2 n = 1,2,3 ...
• Photons are absorbed/emitted when electrons change orbits.
