Ability of an atom attract e (in a covalent e- = high E SEE TIFFANYS CHEMISTRY PAPER Rank in size from largest to smallest S and Mg and Calcium 1 2 3 Rank in IE: N Ga As Rank in EN: S Br Cl Smallest Largest Size S Mg Ca IE Ga As N EN ?? ?? Cl ORBITALS AND ENERGY 1. As Z increase, E of the entire set of orbitals increase 2. Compose #1: as and C or 1s are Na 3. Comparison #2 a. Valence orbitals can diff. atoms smaller atoms = lower E valence orb i. 2s on Li or 3s on Na Smaller atoms = lower E valence orbital 4. Ionization e- to O (top) a.
