So my textbook says the equation for this is 4πr²dr(psi)² It also gives the volume of the shell formula 4/3π(r+dr)³ - 4/3πr³ which I understood But what is the proof for the radial probability distribution curve equation mentioned above?

Sorry it's a bit long so i was watching Action labs video on how neutron stars are formed and in that he says " if there's enough mass, then the mass will keep on collapsing in on itself in the star and will collapse more until actual electrons are so close that the only thing that is stopping th...

I searched everywhere, but I couldn't find a straight answer how can I get a SMILES string, just by writing the name of my chemicals. For example I have a monomer named: 2-(2-(2-((4'-methoxybiphenyl-4-yl)oxy)ethoxy)ethoxy)ethyl acrylate Obviously it is not easy to figure the SMILES code out by my...
