CH 301 Study Guide - Midterm Guide: Periodic Trends, Valence Bond Theory, Lattice Energy
Document Summary
Exam 2 was all about atomic theory and bonding. E photon = (6. 626 x 10 -34 )v = hc/ . E k = ( )mv 2 = hv - . Z eff = z - (# of core electrons) No two e - can have the same set of four quantum numbers. How much charge is in a space. The larger the charge, the smaller the ion. Highest charge densities are due to small size. Wavefunction number - 1 = number of nodes exam 3 was all about bonding theories and imfs. Vsepr (valence shell electron pair repulsion) theory linear trigonal planar bent tetrahedral trigonal pyramidal trigonal bipyramidal seesaw bent. Li 2 -> n 2 lin likes pie (start with 2p orbitals first) O 2 -> f 2 (start with 2p first) Two * 2p are directly after the 2p and 2p. Bond order = (0. 5)(e - bonded - e - anti-bonded)
