Document Summary
Chapter 13 lewis dots for structure and shape (c&p 3rd ed) incl organic naming. 6th, 5th and 4th ed : lewis dot recognition exercises 1-6 problems 1,3, 9,19, 25, 31, 33, Big change here from ch 11 : we now have molecular orbitals , not the s & p atomic orbitals of individual atoms that we learned in ch 11 so the rules are different. The new rule is that you can add up all the valence e-s from the p-table and distribute them wherever they need to go. A lewis dot diagrams are used to decide how atoms are arranged in compounds made from main group elements that obey the octet rule. B rules for figuring out the diagram using ccl4 as an example. 1 calculate the total number of valence electrons in the molecule by adding up the a numbers from the periodic table. C has 4 and 4 cl have 7 each =32 electrons.
