How find spin quantum number

1.	How find spin quantum number
Answer» In one orbital, the orientation of the two electrons are always the opposite of each other. One electron will be\xa0spin\xa0up, and the other electron is\xa0spin\xa0down. If the last electron that enters is\xa0spin\xa0up, then ms = +1/2. If the last electron that enters is\xa0spin\xa0down, then the ms = -1/2.
