AI Thread Summary
Understanding orbitals, shells, subshells, and electron configuration can be challenging for many learners. Users in the discussion seek reliable resources to clarify these concepts, expressing frustration with the quality of available information. Several websites are recommended, including Purdue University's chemistry page and various educational sites from Florida State University and Fordham Prep. Caution is advised when using Wikipedia due to quality issues, and cross-referencing is encouraged. Overall, the discussion emphasizes the need for clear, accessible explanations of atomic structure based on quantum mechanics.

I'm having trouble understanding anything dealing with the subject of orbitals, shells, subshells, electron configuration, etc. I'm sure no one on this site is going to want to explain it to me in full or anything like that; I'm not expecting it. Can anyone suggest a website that explains this subject matter? I'll continue looking myself but I'm not finding anything that great. So any help or suggestions would be much appreciated.

id suggest just typing in atomic structure in google...and make sure its the one defined by quantum mechanics
 
or just go with Astronuc's sites, lol:P
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
