Part 1: Calculating the Energy Levels of the Hydrogen Atom In 1886 Balmer showed that the lines in the spectrum of the hydrogen atom had wavelengths that could be expressed by a rather simple equation. Bohr, in 1913, explained the spectrum on a theoretical basis with his famous model of the hydrogen atom. Energy levels for the hydrogen atom can be calculated from the following equation: E = -1312.04/n2 Using this equation, calculate the energies of the ten lowest levels...
