Please type your subject in the School Subject box. Any other words are likely to delay responses from a teacher who knows that subject well.
Since this is not my area of expertise, I searched Google under the key words "Lewis structure" to get these possible sources:

http://en.wikipedia.org/wiki/Lewis_structure
http://www.ausetute.com.au/lewisstr.html
http://www.stolaf.edu/depts/chemistry/courses/toolkits/123/js/lewis/
http://www.chem.lsu.edu/htdocs/people/sfwatkins/MERLOT/drawlewis/dls.html
http://antoine.frostburg.edu/chem/senese/101/bonds/faq/simple-lewis-structures.shtml

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps.
