Give two reasons why the Bohr theory did not stand thetest of time.
Bohr's model of the atom can be termed a "quantum" model of the atom because electrons and protons are equal the nucleus is positive each electron can possess only specific amounts of energy the potential energy of electrons is measurable
of the velocity in (c) to the speed of light? 2. In 1913 Neils Bohr proposed a model for the hydrogen, now known as the Bohr atom, that explained the emission spectrum of the hydrogen atom as well as one-electron ions like Het. The model permits the electron to orbit the nucleus by a set of discrete orbits where each orbit is associated with an integer value n, known as the principal quantum number. Depending upon the orbital occupied by the electron, the energy of the hydrogen atom (or one-electron ions) can only assume the following discrete values 1terd 30 tF aconstant En n2 prineiple 2 S1 where RH 2.18x10-18 J is the Rydberg constant and Z is the number of protons in the nucleus.(a) List the energies of the hydrogen atom for the first three orbits (n-1, 2, and 3).*(b) Compute the energy absorbed by the hydrogen atom when the electron is excited from the lowest orbit (n 1) to the third lowest orbit (n 3).

49. Which of the following correctly identifies how Louis de Broglie's concept of the electron as a particle-wave helped to explain energy levels for an electron in an atom. A. de Broglie described the electron orbit as a circular standing wave pattern with a specific angular momentum as required by the Bohr hypothesis. B. de Broglie described the electron as a planar wave with a non- specific frequency as required by the Bohr hypothesis. C. de Broglie described the electron as a wave whose range of frequencies was continuous and thus allowed for all the possible electron energies predicted by Bohr. D. de Broglie described the electron as a spherical wave whose wavelength was dependent upon the speed with which it orbits the nucleus, as needed to explain the Bohr hypothesis.
