Define quantum number |
|
Answer» Set of 4 numbers which give complete information of atom ?? Quantum numbers are a set of values that describes the state of an electron including its distance from the nucleus, the orientation and type of orbital where it is likely to be found, and its spin.The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers.\tThe principle quantum number (n) is the number of the electron\'s shell.\tThe angular momentum quantum number (l) is the type of orbital (s=0, p=1, etc).\tThe magnetic quantum number (ml) is the orientation of the orbital (integers from –l to l, for p = -1, 0, 1).\tThe spin projection quantum number (ms) is the spin of the electron (either -½ or ½). |
