Unformatted text preview: the metal Pb. 6. For the following four molecules, assign Lewis Dot Structure, Electronic Geometry, Molecular Structure and most likely hybridization. If there are resonance structures, show them. PF 5 SO 4-2 IF 3 NO 3-1 7. In class we discussed that the octet rule really only had to be followed by four atoms in molecule formation. Identify the four atoms and explain why the other atoms may be exceptions to the rule. 8. For the following electron configurations, identify which would be that of the ground state of an ion and which would be that of an atom. Identify a possible element (specify charge) and also identify which one(s) cannot possibly a ground state configuration. a. ns 2 (n-1)d 8 b. ns (n-1)d 8 c. ns 1 (n-1)d 8 d. ns 1 (n-1)d 4 e. ns 1 (n-1)d 5 f. ns 2 (n-1)d 8 np 2 g. ns 2 (n-1)d 10 np 2 h. ns (n-1)d 10 np 2 I. ns (n-1)d 10 np j ns 2 (n-1)d 10 np 4...
