WebThe equation is delta E = RH (1/n2final - 1/n2 initial). Here, our RH value is 2.18 x 10-18 Joules. We’d use this version of the Bohr equation when they’re giving us or discussing two shells like you’re going from shell 3 to shell 1 and they reference energy. Again, if they’re talking about two shells, and they’re referencing energy ... WebIn Bohr’s model of the hydrogen atom, the electron moves in a circular orbit around the proton. The electron passes by a particular point on the loop in a certain time, so we can calculate a current I = Q / t I = Q / t.An electron that orbits a proton in a hydrogen atom is therefore analogous to current flowing through a circular wire (Figure 8.10).In the study … WebNov 4, 2014 · Video transcript. - In the Bohr model of the hydrogen atom we have one proton in the nucleus.
