In lab we studied the Bohr model of the hydrogen atom which is verified exactly with quantum mechanical calculations. From quantum mechanics we also find that Bohr’s equation can be used for any one-electron cation like He+, Li2+, Be3+ etc, by including the atomic number, Z, of the cation in the equation with Bohr’s constant (): En= -Z2n2(Accurate for any one-electron cation with atomic number Z) Use this equation to calculate the energy (J) of the first and second energy...
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...
