an electron is confined to a box. in the third allowed energy level the energy is 27 eV. Find the length of the box and the energy in ground state.
An electron is confined to a box of width 10 nm. How much energy must be acquired to boost it into the first excited state, n=2, from the ground state?
(20 points) Treat the hydrogen atom as a one-dimensional problem, where the electron is confined to the diameter of the atom in the first excited state (n-2). a.) Use the uncertainty principle to estimate the minimum kinetic energy of an electron in this state, assuming that the uncertainty in position equal to it's diameter. (Note: Relativistic corrections are not necessary). b.) Assuming this excited electron only remains in this state for 0.1 ns, before emitting a photon and returning to...
Assume that four electrons are confined to a one dimensional box 4.95 ✕ 10−10 m in length. If two electrons can occupy each allowed energy level, calculate the wavelength of electromagnetic radiation necessary to promote the highest-energy electron into the first excited state.
An electron in the ground state of a hydrogen atom (-13.6 eV) absorbs a 10.2 eV photon and jumps to the first excited state. What is the energy in eV of the first excited state?
Energy (eV) 1. The figure to the right shows the first few energy levels for lithium. The ground state for the valence electron (the electron most likely to change 4 energy levels) is the 2s state which is why that state is set to O eV. Make a table showing all possible transitions in the emission spectrum. For each possible transition indicate A. Energy change of possible transition. B. At for the transition.
