paths like planets around the sun occupy regions of space called orbitals These orbitals characterized by specific shapes and energy levels are described by quantum numbers Principal Quantum Number n Determines the energy level and size of the electrons orbital Higher n values correspond to higher energy levels Angular Momentum Quantum Number l Specifies the shape of the orbital Values from 0 to

orientation of the orbital in space Spin Quantum Number ms Describes the intrinsic angular momentum spin of the electron which can be either 12 or 12 These principles dictate how electrons fill the orbitals following the Aufbau principle electrons fill the lowest energy orbitals first Hunds rule each orbital in a subshell is singly occupied with parallel spins before any one orbital is doubly occupied and the Pauli exclusion principle no two electrons in an atom can have the same set of four quantum numbers The Argon Orbital Diagram A Visual Representation The argon orbital diagram typically displays the filling of orbitals from the lowest energy level to the highest For argon atomic number 18 the diagram shows 1s2 2s2 2p6 3s2 3p6 This notation indicates the number of electrons in each orbital For example 1s2 means two electrons are occupying the 1s orbital The diagram visually maps these filling patterns highlighting the energy levels and subshells Think of this like
