Lewis Dot Structures of Covalent Compounds
In this interactive and animated object, students distribute the valence electrons in simple covalent molecules with one central atom. Six rules are followed to show the bonding and nonbonding electrons in Lewis dot structures. The process is well illustrated with eight worked examples and two interactive practice problems.
Which rule is used when constructing Lewis Dot structure? Are there any exception to this rule? Construct Lewis Dot structures of four compounds different from the once in tutorial
8 valence electrons
Count the amount of valence electrons. The dots can only be paired with each other if there are 4 dots on each side. helium
How many valence electrons the element has. You know this by the group number. Noble gases in group 8 either have 2 or 8 valence electrons.
Find the total amount of valence electrons, place the electrons around each of the atoms until it has a total of 8 electrons, if there are not enough electrons use double and triple bonds.
GREAT!! Learned more going through this then in my classroom for 2 days, it actually made sense!Posted by Maggie S on 1/8/2012 10:16:14 PM Reply
Thank you! very easy to understand.. I my self am a student... it helped me so much! Great site!!Posted by Randy Rivas on 10/20/2011 9:31:32 PM Reply
Thank you so much!!! This helped a lot!!! I was really stuggling with covalent bonding and lewis dot diagrams, but after Wisc-online helped me out, i feel like i am ready to accomplish anything!!! hahah lol Hopefully i can pursue my dream of being a professional chemist. Once again, Thank you so much <3 :) - Lynsey GarfinkelPosted by Lynsey Garfinkel on 11/6/2013 12:49:00 PM Reply
