ST. LOUIS -- When the Boston Red Sox signed Mike Napoli this past winter, there were a number of possible outcomes. He could hit a little, the way he had in 2012, putting up an OPS+ of 113. He could hit a lot, like he had in 2011, with a 173 OPS+ and 30 home runs. Most likely, he'd fall somewhere in between.
The fourth quantum number is the spin quantum number, s. There are only two values for s, +Â½ and -Â½. These are also referred to as 'spin up' and 'spin down'. This number is used to explain behavior of individual electrons as if they were spinning in a clockwise or counterclockwise.
The properties of an atom's electron configuration are described by four quantum numbers: n, â, m, and s. First Quantum Number. The first is the energy level quantum number, n. In an orbit, lower energy orbits are close to the source of attraction. The more energy you give a body in orbit, the further 'out' it goes. If you give the body enough energy, it will leave the system entirely. The same is true for an electron orbital.
