The orbital quantum number for the electron in a hydrogen atom is 1 = 6. What is the smallest possible value for the total energy of this electron? Emin = eV Submit
Part A According to the quantum-mechanical model for the hydrogen atom, which transition produces light with longer wavelength: 3p to 2s or 4p to 2s? Match the words in the left column to the appropriate blanks in the sentence on the right. Reset Help smallest The transition with the energy difference will produce the longer wavelength; therefore, 4p according to the quantum-mechanical model for the hydrogen atom, the to 2s 3p transition would produce light with the longer wavelength. largest...
The quantum-mechanical treatment of the H atom gives the energy, E, of the electron as a function of n: where h is Planck's constant, me is the electron mass, and a0, called the Bohr radius, is 52.92×10−12 m. Calculate the wavelength in nm of the photon emitted in the jump between n = 1 and n = 4.
In Bohr's model of a Hyodrogen atom, electrons move in orbits labeled by the quantum number n. Find the radius, in meters, of the orbit of an electron around a Hydrogen atom in the n = 5 state according to Bohr’s theory.

(a) (i) Discuss the eigenvalues of a quantum mechanical harmonic oscillator (QMHO). (ii) What is the significance of the eigenfunctions of the QMHO to be non-zero outside the harmonic potential? Give an example to illustrate your answer.
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 A According to the quantum-mechanical model for the hydrogen atom, which electron transition produces light with the longer wavelength: 3p - 28 or 4p 3p? Match the words in the left column to the appropriate blanks in the sentences on the right. Reset Help closer to As the n level increases, the energy and thus the levels are each 4p† 3p would have a greater energy difference than the other. Therefore, the transition transition from increases farther...
