It is my understanding that the spin magnetic quantum number, m_s, has a value of either 1/2 or -1/2. Which way does the electron spin if it has a m_s value of 1/2 and if it has a m_s value of -1/2?
The Ms values denoting the spin/direction of the electrons in an orbital are merely RELATIVE values to emphasize how electrons paired in the same orbitals must have opposite spin. If one electron has a spin in a given direction and is assigned a +1/2, the other must have a -1/2 spin and visa versa.
So does this mean that the +/- signs are relative to each other? And also, when you draw a pair of electrons of a lone electron, do you by convention draw then up or does it not matter meaning you could draw them pointing down?
On the most recent test there was a question that asked for all the possible values that a spin quantum number can take for a specific electron. How do you determine this? Is it always +/- 1/2?
