5 Lewis Dot Structures That’s right….Lewis Dot Structures Key Point #1: Lewis Dot structures only show the number of valence electrons in an atomValence electrons are the only electrons involved in bondingValence electrons are the most important electrons
6 Drawing Lewis Dot Structures Write element symbolDetermine number of valence electronsPlace single dot on right side and add dots one at a time counterclockwise.Ex.
9 LET’S PRACTICE!Each person will receive 8 M&Ms NO EATING UNTIL WE ARE DONE WITH PRACTICE When I put an element on the board, you must create the Bohr model for that element using your M&Ms to represent electrons When we are done with practice, you can feel free to eat your candy.
15 How many valence electrons in boron? Draw the following independently in your notes, and then we will come back together to review. These will be graded as your exit ticket – you will turn them inBoronNeonFr
16 If we have time…..You may begin your review packet for the exam
