Document Summary
Exam 1 starts next wed. , run thu thurs. Importance of nodes # more nodes = higher energy. Relationship to cartesian coordinates check pdf for relationships (sines, cosines) 2-(zr/a(0)) = 0 - nodes in the wavefunction. Not 1s and 1p, no such thing as 1p orbital. Not 1s and 2s not the same amount of energy. 3s, 3p, and 3d is the correct one. Different energy in every atom except hydrogenic atoms. Changes potential energy in schrodinger equation, s p and d are no longer degenerate. In a h atom, how many 3p orbitals exist? p orbitals always come in sets of 3. In a h atom, how many 4p orbitals exist? p orbitals always come in sets of 3. 2 radial and planar nodes: s - 0 planar, p - 1 planar, d - 2 d has a clover-shaped formation.
