Document Summary

The quantum mechanical model of the atom in the atomic world, the behavior of subatomic particles is both particle-like and energy-like. Heinsberg uncertainty principle: we can"t know both the position and the momentum of the electron in an atom. Schrodinger equation: mathematical relationship predicting the probable locations of an electron in an atom. Quantum # n l m ms principal size of orbital angular momentum # shape of orbital. 0 1 n-1 magnetic quantum # orientation of orbital in space. Integer values between l and -l spin quantum # angular momentum of. Number of electrons in each type of orbital. Atomic orbital of atomic orbital s p d f. Shell s s , p s , p , d s , p , d , f. 32 n principal quantum number: as n increases, electrons can be found at farther distances from the nucleus.
