I am having some serious confusion regarding the following terms:
1) According to Bohr's quantization of angular momentum, mvr=nh/2π. My question is what kind of angular momentum is that? Is the the "orbit angular momentum"?
2) Orbital angular momentum= {l(l+1)}1/2 BM. Again, I fail to understand what it's significance is.
3) I have been told that the spin angular momentum = {S(S+1)}1/2 BM where S=n/2. However, I also read somewhere that the value of S is fixed for objects spinning around their axis (1/2 for an electron, +-1/2 is the spin quantum number). So, which of them is correct?
4) Whenever we say "magnetic moment", do we mean the "spin only" magnetic moment which is equal to {n(n+2)}1/2 BM?
5) This one is not related to quantum numbers. We know that de broglie wavelength for an unchargen particle in non-relativistic situation=h/p where p is the momentum (=m*v). For gaseous molecules, we take 'v' as the root mean square speed (={3RT/M}1/2). My question is, in the formula or root mean square speed, 'M' is the molar mass of the gas, so to calculate the momentum (=m*vrms), do we have to take the molar mass of the gas in place of 'm'?
Please have a look at them and reply as soon as possible. Thanks in advance.
