Lewis Dot Diagrams Lesson Review

What is the goal of the Lewis Dot Structure?

• To determine the electron position.

• To show the element's valence electrons & bonding capabilities.

• To search for the number of electrons in an individual atom.

How many valence electrons should Lithium have in its Lewis dot model?

• 1

• 2

• 3

Which of the following describes a valence electron?

• Innermost from nucleus

• Least energetic

• Determines chemical properties and bonding

How many valence electrons are every atom trying to obtain?

• 4

• 6

• 8 (2 in a few cases)

Place the steps of making a Lewis Dot Diagram in the correct order

• Write element symbol

• Place one dot per side initially

• Visualize/draw box around symbol

• Add dots up to 2 per side until all are used

• Determine number of valence electrons

Fill in the blanks with all of the elements which could have 3 valence electrons. PLACE THEM IN INCREASING ATOMIC ORDER.​ (a)   ​ (b)   ​ (c)   ​ (d)   ​ (e)  

• B
• Al
• Ga
• In
• Tl
• Be
• Ge
• Ir
• Ti
• As
