Energy levels Definition and 267 Threads

"primes" as Energy levels...(eigenvalues of a certain operator) I have heard about the Riemann Zeta function to be some kind of physical partition function..my question is..could we consider primes as "Energy levels" (eigenvalues) of a certain partition function or operator?..in the form that...

how can we directly demonstrate the existence of energy level within an atom??

The diagram shows some of the energy levels of an electron in a mercury atom. Level Q represents the lowest possible energy level. (a)Explain why a line spectrum results from an atom with such energy levels. (b) Calculate the energy change in joules when the electron moves from level...

For a 1D infinite well, The energy levels of an electron trapped inside is dependent on the length of the well. The longer the length, the less its energy will be for each state. I am aware how the formula is derived. The main form of the formula is a solution of Schrodinger's equation which...

The question is: So I have the equation to find the energy in an infinite well… \[ \begin{array}{l} E_n = n^2 \frac{{\pi ^2 (\hbar c)^2 }}{{2mc^2 L^2 }} \\ L = 2*10^3 nm \\ m = 5.11*10^5 eV \\ \hbar c = 197.33eV*nm \\ \end{array} \] Using this, I find n=1 to equal...

Hi: a) an atoms electron is in the ground state (4.11*10^ -17). An electron with ke 5*10^-17 collides with the atom, what happens to the energy. b) What could subsequently happen to the electrons in the higher energy levels help please

If an atom has a ground state energy level of -10.4eV then why is the ionisation energy 10.4 x 1.6 x 10^-19J ? Wouldn't that amount of energy just cause the electron to move to the highest energy level? I would have thought that the energy required to ionise the atom would be any value greater...

Hi Guys, Because of the absorbtion and emmision spectrum we know that atoms have quantised engergy levels. For example for an electron to jump from ground state to the first excited state in a Mecury atom, a photon with the exact energy of 4.9eV is required. Now my question is what would...

Hey guys I was wondering something probably very simple. Would I be able to determine the force something has been applying if I simply know its final kinetic energy and displacement? And I remember this one equation where something = Integral of F * dx. I swear I am forgetting everything...

My instructor was telling what would be on the upcoming test and he said something about:Given the velocity of an electron, the work function of a certain metal, and final energy level. We should be able to find the intial energy state. Sound pretty easy... to easy but here is what i was...

Where can I find the different energy levels (in eV) for Li (2+). I can't seem to find it in my textbook or on the internet.

Number of energy levels... I have been told that as were go further away from the nucleus, the energy levels get closer and closer together - do we get to a stage where we get no more? I assume we must because any energy above this causes the substance to ionise (ie the ionisation energy); but...

In a post below relating to Hawking radiation, Chronos linked to a page that expressed the existence of virtual pairs as a product of energy and time limited by the Heisenbug uncertainty principle: \Delta E\Delta t\geq\frac{\hbar}{2} This simplified view neatly illustrates one of the...

How do I calculate the number of electrons with a given energy in a sample of hydrogen atoms at a certain temperature? For example how many electrons would be in the n=2 level at 3 Kelvin? And does it matter whether or not hydrogen is gas or liquid or solid i.e is a different calculation...

When radiation with a continuous spectrum is passed through a volume of hydrogen gas whose atomes are all in the ground state, which spectral series will be present in the resulting absorption spectrum? Where do i even start?

Are rotational energy levels of a molecule in general equally spaced or does the spacing increase with energy? How about a diatomic molecule; I have seen a derivation showing that the rotational levels in a diatomic molecule are equally spaced, but when drawn in an energy level diagram they...

i am having problems with the atom model part of physics, i know that the current model stats the electron location is a probability and all, its when i get to the wavelength and the energy, with all the ionization and the spectrums that i don't understand... how can i find the energy level...
