What is Hydrogen atom: Definition and 408 Discussions
A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.In everyday life on Earth, isolated hydrogen atoms (called "atomic hydrogen") are extremely rare. Instead, a hydrogen atom tends to combine with other atoms in compounds, or with another hydrogen atom to form ordinary (diatomic) hydrogen gas, H2. "Atomic hydrogen" and "hydrogen atom" in ordinary English use have overlapping, yet distinct, meanings. For example, a water molecule contains two hydrogen atoms, but does not contain atomic hydrogen (which would refer to isolated hydrogen atoms).
Atomic spectroscopy shows that there is a discrete infinite set of states in which a hydrogen (or any) atom can exist, contrary to the predictions of classical physics. Attempts to develop a theoretical understanding of the states of the hydrogen atom have been important to the history of quantum mechanics, since all other atoms can be roughly understood by knowing in detail about this simplest atomic structure.
How would I show that the most probable values of r for the n-1=l states of hydrogen are
r=n^2a where a is the Bohr radius
I know these values must satisfy the equation d/dr(unl)^2=0
Consider a hydrogen atom in the n = 1 state in a magnetic field. For what value of the magnetic field is the splitting between the s = +1 and s = -1 levels equal to .000093 eV?
I have asked many people and searched many sources for the answer to the following question but have yet to reach a satisfactory conclusion.
When solving the hydrogen atom by separation of variables, for the angular equation, you come across the O.D.E.
d^2/(do)^2 (F) =...
Here's my question...
For a hydrogen atom in the ground state, what is the probability to find the electron between 1.00a and 1.01a, where a is the Bohr radius? It is not necessary to evaluate any integrals to solve this problem.
I know that P(r)=r^2*(R(r))^2. I used the R(r) expression...
Hey all. I've got a physics question due tonight (Friday) at 11pm CST and I'm stumped. Any input at all would be helpful, thanks!
A hydrogen atom, when vigorously perturbed, can emit light with a frequency of 6.16·10^14 Hz. When the same light from hydrogen atoms in a distant galaxy is...
please help me study by answering a few questions.
consider a hydrogen atom with energy levels En= -(13 eV)/(n^2)
this atom is bombarded by photons of E = 15 eV.
What is the incoming photon frequency?
What are possible kinetic energies and speeds of the emerging electrons?
What is...
Using the ground state of the hydrogen atom
Psi 1,0,0 = sqrt([pi]*a3) * e-r/a
I get <r> the expected radius as <r> = 3a/2 where a = Bohr radius.
Anybody happen to know if this correct?
It would have been cooler if the Bohr radius in physical constants were <r> and the scale factor...
