CHEMISTRY Lecture Notes - Lecture 1: Subatomic Particle, Pauli Exclusion Principle, Principal Quantum Number
Document Summary
Quantum numbers are numerical representations of the energy, angular momentum, and orientation of an atomic or subatomic particle within an atom in quantum physics. Four quantum numbers exist, and they are: principal quantum number (n): The energy state of an electron within an atom is described by this quantum number. The larger the number of n, which is a positive integer, the higher the electron"s energy level: the electron"s orbital"s form is described by the azimuthal quantum number (l), which is a quantum number. Its integer value, which ranges from 0 to n-1, defines the electron"s angular momentum: the magnetic quantum number (m) defines how the orbital is oriented in space. It is a number with a value between -l and +l: spin quantum number (s): the spin, or inherent angular momentum, of the electron is described by this quantum number. The condition of an electron inside an atom is completely described by these quantum numbers taken together.
