Homework Statement Homework Equations where The Attempt at a Solution I tried to integrate (7-32) over all values of r (i.e., from negative infinity to positive infinity) and set it equal to 1, but the result was too messy and was divergent. Am I making the right approach?

Hey, I kind of understand the process of the 21 cm emission of the atomic Hydrogen, I know how rare it should be but still it is detectable in our Galaxy due to the huge amount of atomic hydrogen it has. However, I was wondering if it is possible to detect the 21 cm emission line in a...

Good day With reference to the following article: https://hal.archives-ouvertes.fr/hal-00506468 The measured frequency is given as 2922742936.729(13)MHz but right at the end of the article, the following is written: "The hyperfine structure of the 1S level is well known and that of the 3S...

Atomic Hydrogen gas cloud to Star! what would be different about stars and their formation if interstellar medium only has atomic gas and nothing else? how would it affect stellar interior and energy production? My guess is that since atomic hydrogen is less massive than molecular...

One molecule of diatomic hydrogen H2, passing through an electric arc between tungsten electrodes, splits into hydrogen atoms by absorbing a considerable amount of heat: H2 + 103Kcal = H + H = H2 + 103Kcal Atomic hydrogen, recombining into molecules, being unstable, after 0.5 seconds, gives a...

Homework Statement Despite extensive searches of the web and my old honors freshman chem text, I have yet to find a kj /mol value for either the standard Gibbs' Free Energy (Delta-G-naught (298° K)) or standard ENTROPY (Delta-S-naught) for the ionization of gaseous ATOMIC Hydrogen (or for...

Homework Statement The first few lines of the Balmer series for atomic hydrogen lie at the wavelengths λ = 656.46, 486.27, 434.17, 410.29nm, ... Find a value for RH, the Rydberg constant for hydrogen. The ionization energy I is the minimum energy required to remove the electron. Find it from...

Calculate the polarizability "a(lpha)" of atomic hydrogen in terms of R Homework Statement A simplified model of a hydrogen atom is that the electron cloud is a sphere of radius R with uniform charge density and total charge -e (The actual charge density in the ground state is nonuniform)...

Homework Statement According to the Bohr theory, what is the ionization energy of atomic hydrogen in kJ/mol? Homework Equations Bohr equation: E = (-2.18 x 10-18 J)(1/n2) The Attempt at a Solution I don't have any general idea on how to do this problem :( please help! The answer is...

I spent my Thanksgiving trying to solve my homework and I will need some help: 1)For fixed electron energy ,the orbital quantum number l is limited to n-1.We can obtain this result from a semiclassical argument using the fact that the larges angular momentum describes circular orbits,where...

Electrons are accelerated through a potential V into a cloud of cold atomic hydrogen. A series of plates with aligned holes select a beam of scattered electrons moving perpendicular to the plates. Immediately beyond the final plate, the electrons enter a uniform magnetic field B perpendicular to...

Please I need detailed information about the ionization of atomic hydrogen , quantum states , values of energies ... etc
