5. The radii of Na and Na* are 1.86 Å and 0.95 Å respectively (Å = angstrom = 10-10 m). Assume that atoms and ions are spherical. Vsphere = (4/3) t r3 a) Calculate the volume of a neutral sodium atom in Å³ (no need to convert). b) Calculate the volume of a sodium ion in Å3. c) Calc. the % change that occurs when Na becomes Na*. Comment on the sign and magnitude. % change = (Vion– Vatom) x 100 Vatom

PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.
