CHEM 130 Lecture Notes - Lecture 7: Atom, Principal Quantum Number, Pauli Exclusion Principle
Document Summary
10: dxy, dx2, dy2, dx2y2, dz2 can all hold 2 electrons so 10 in all. n=4 l=2 ml=-2,-1,0,1. Clicker: why is the following electron con guration impossible?n= 5, l= -2, ml= -2, ms= . For atoms with multiple electrons, the orbitals of the same principle quantum number (n) are no longer degenerate due to differences orbital shape. 2. 11 the aufbau principle: electrons are added one by one to the orbital, aufbau principle (building up principle): If you look at the diagram, you ll along the diagonals. Clicker: the ground-state electron con guration for nickel 1s22s22p3s23p238 is best abbreviated as what (using noble gas con gurations). [ar] 4s23d8: noble gas electron con guration: you can abbreviate any electron con guration by representing the inner or lower level electrons by a noble gas. 1a2 > 3p6 = ar: concept check: give the electron con guration for zinc.
