13 Draw the Lewis Structure for PCl 5 Sometimes there are two or more Lewis Structures that can be drawn For example there are two equivalent Lewis structures for NO 2 as shown below Check to make sure that each is a correct Lewis structure The possible structures are called resonance structures and are drawn with a double headed arrow For the following neutral molecules calculate the total number of valence electrons and draw the correct Lewis structure For neutral molecules it s okay to assume the normal numbers of covalent bonds apply and that the central atom is the first non H element in the formula 4 CH4 4 4 1 8 ve total 5 CH3Cl 4 3 1 7 14 ve
LEWIS STRUCTURES PRACTICE WORKSHEET Draw the Lewis Structures for each of the following molecules If you are not sure if your structure is correct do a formal charge check You should consult the Lewis structure rules and a periodic table while doing this exercise A periodic table will be available for the exam but the list of rules will If you get stuck try asking another group for help For each of the following draw the Lewis dot structure give the electron arrangement E A and the molecular geometry M G P F 5 C S 2 B r O 3 N H 4 S C l 4
