Blake 10-15-08 Chemistry Ex 1: Which quantum number corresponds to the orientation of the orbitals? 1. Secondary 2. Principal 3. Magnetic - ANSWER 4. Spin Ex 2: How many 4s electrons does a vanadium (I) cation have? 1. 0 - ANSWER 2. 1 3. 2 4. 4 - For the transition metal, it takes the electrons from the 4s orbital and puts them into the 3d orbital Ex 3: Which is the largest atom? 1. Li (79 G/MOL) 2. Cl (35.5 G/MOL) 3. F (19 G/MOL) 4. Na (32 G/MOL) – ANSWER Explanations - N corresponds to size (down column) 1. N = 1 (0) 2. N = 2 (1) 3. N = 3 (2) 4. N = 4 (3) - The nucleus attracts the electrons (across row) - TOP TO BOTTOM (SMALL TO LARGE) - RIGHT TO LEFT (LARGE TO SMALL) - IONIZATION ENERGY GOES UP AS YOU GO FROM RIGHT TO LEFT

Unformatted text preview: Trends in for IE 1. Definition!!!-Energy change for the removal of 1 electron from a neutral isolated atom. 2. Equation corresponding to definition-Li(g) = Li + + e-∆ H = _520 kJ 3. Down column (n change)-N bigger-Electron farther from nucleus, easier to remove Trends in ionization Energy 1. Down column (n changes) 2. Across row (Z change with n constant)-As you go across the row it increases-Increased nuclear charge pulls electron closer 3. Exceptions across row (sublevel change or pairing energy)-Be (s 2 )-B (s 2 p 1 )-N (p 3 )-O (p 4 )...
