If you google "silver electron configuration", you'll get the answer that it is Kr 4d10 5s1. So, "Kr" tells you that silver electron configuration is like krypton's plus additional 11 electrons. Ten of them fill up 4d shell completely which does not have any angular momentum because there are 5...

Density does not matter. Relating macroscopical phenomena of thermodynamic equilibrium to atomic level events was subject to much research and is legitimate scientific question. Quick was to relate temperature and velocity of a particle is through equipartition - let say you have pointlike...

Yes, actually there is no reason that I'm aware of for n to be limited above and, should that be true, expectation of the electron's distance from the nucleus rises without limits, with n2 I believe. Consequence is that with n = 1 000 000 you'd have hydrogen atom larger than Earth. Of course...

Hello! Similar question arose at another forum, basically guy asked what is the color of the hydrogen at the temperature T. I provided as much help as I could and he actually found solution which I think is correct. This said, I'm not sure that the numbers you got for the population of states...

A very fuzzy question, because I'm not sure what are you suggesting. A few notes: We didn't stop. When you say it like that it seems like you are implying that Newton's law is result of a science community consensus to obey the Great Master, rather than meticulously verified principle of...

Hello! I've heard suggestions (e.g. Griffits in his "Introduction to Elementary Particles") that if singlet gluon could be photon itself then it would be beautiful unification of the electrodynamics with strong force, but have never actually heard of suggestion that it's connected to gravity...

In essence - yes. Maybe this mental image will help you. Photon (quanta of light) and proton (a baryon, nucleus of hydrogen) are racing across the galaxy. Let's say that proton has so much energy and it's so fast that after 100 years of racing, it's only 1nm behind photon. Let us also assume...

Why do you think forces cancel? As far as I see it, they most certainly do not! Let say dipol is oriented to +z and test charge is positive. Repulsive force z component will be negative, and attractive force by negative part of dipol will have z component also negative, so you don't have...

Try spinning around yourself and as you revolve, look at Andromeda galaxy up, in the skys: does it speed with warp 10? The two situation are not equivalent: inputing energy to rotate a human body is not the same as putting entire universe into a frenzy spin.

Had it for some time now ... enjoy your physics :)

Hello! Maybe you'll find http://www-d0.fnal.gov/hardware/cal/lvps_info/engineering/elementmagn.pdf" usable.

One way to see it is through equipartition theorem stating that every degree of freedom (DoF) in thermodynamic equilibrium takes up kT/2 energy on average. If you start with finite number of matter DoF possessing all available energy (i.e. an object at temperature T) coupled to an "array" of...

Hello! I was thinking about what would happen if an atomic gas was allowed to expand in vacuum and concluded I don't have much of a handle on the subject, so if anyone would help me out - I'd really appreciate it. So, let's say we have an ideal gas in a container located in vacuum...

Well, I'm not sure this is true for any V(x). Namely, if you take V(x) = 0, then you would not get <p> = 0, obviously. If you are thinking of bound states, it kinda feels one could devise up such V(x,t) to get <p> != 0. But I'll think this trough ...

Hello! I'm redesigning my never-to-be-finish sci-fi novel, yet another futile to come up with scientifically based interstellar travel propulsion. My latest consideration is based on article[1] and possible extensions of those ideas. Anyway, I'm looking for an independent opinions on the...
