Unformatted text preview: Orbital Energy Levels for Hydrogen and Multielectron Atoms Each electron in an atom occupies an orbital and each orbital has a specific energy level Spin Quantum Number Spin quantum number (m s ) assigns a spin t o electrons. m s can have either of two values: +1/2 ( ) or -1/2 ( ) Orbital can only hold two electrons which must have opposit e spins According t o the Pauli exclusion pr inciple, no two electrons can have the same four quantum number Four Principle Quantum Numbers to describe wave function Wave function: describes energy level of orbital and 3d shape of region occupied by electron n 0,1,2,3 l no larger than n-1 m l +l to -l m s-1/2 or + 1/2 Atomic Spectra Electron Transitions between Different Energy Levels Lead to Light Emission Orbital Energy Levels for Hydrogen and Multielectron Atoms Each electron in an atom occupies an orbital and each orbital has a specific energy level Named series of Lines in the Hydrogen Spectrum Orbital Energy Levels for Hydrogen and Multielectron Atoms Each electron in an atom occupies an orbital and each orbital has a specific energy level Energy Differences between Orbitals and...
