Breakout Room # 4: Gilbert Lewis and The Lewis Dot Structure

by Krystal Wellmann

​Directions: Read the next slide carefully. Then watch the short clip on dot structures. Lastly, answer the two discussion questions.

​Lewis Dot Structures

• ​Gilbert Lewis found an easy way to illustrate bonding.

• ​Gilbert Lewis, a chemistry professor, came up with the system of electron dot structures in 1902!

• ​Bohr diagrams are too complete to illustrate and predict chemical bonds.

• ​Lewis dot structures show ONLY valence electrons.

• ​Lewis dot structures are useful in showing chemical bonding.

​Gilbert Lewis

​Fluorine has 7 valence electrons, and here you see 7 dots.

​A copy of this chart will be in the unit 4 folder. It is best to print a copy or save it for easy access.

Multiple Choice

How many valence electrons does Carbon have?

• 2

• 4

• 16

• 13

Multiple Choice

Which photo below would be the correct electron dot structure for carbon?  (HINT: think about the # of valence electrons from the previous question)
