Understanding Quantum Numbers and Orbital Values

AI Thread Summary
Quantum numbers define the properties of atomic orbitals and the electrons within them. For the orbitals 2p, 3s, and 5d, the principal quantum number indicates the energy level and distance from the nucleus, while the azimuthal quantum number specifies the shape of the orbital. The principal quantum numbers for these orbitals are 2, 3, and 5, respectively, and the azimuthal quantum numbers are 1 for 2p, 0 for 3s, and 2 for 5d. Understanding these quantum numbers is essential for grasping electron configurations and the behavior of electrons in atoms. Resources like the Schrödinger equation and various educational websites can provide further clarification on these concepts.

The question isn't exactly like this but this is the jist of it: Give the values of the quantum numbers associated witht he following orbitals: 2p, 3s, and 5d. I ,frankly, do not understand what they are asking for. So can anyone explain this for me. Thanks.

in 1s or 2p, the number is the principal quantum number, which is related to the radial distance the electron is most likely to be found, and the letter denotes the azimuthal or orbital angular quantum number.

Actually the sites you just gave me were the same ones that I already saw but I got frustrated so I didn't read the whole thing through. Thanks for the help though.
 
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'
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...
