Valence Electron Review

Check in! On your handout, rate your confidence in drawing Bohr models.

Stations Follow the instructions at each station. Leave each station just as you found it!

Post-Station Discussion Which station was the most challenging? Why? What is a common error in drawing Bohr models? What steps can you take to make sure a Bohr model is correct?

Whiteboard Review Practice Draw the Bohr model of Magnesium.

Whiteboard Practice Identify what element this Bohr model represents.

Whiteboard Practice What does the atomic number tell us?

Whiteboard Practice Which has more neutrons: Bromine or Selenium?

Whiteboard Practice How many moles are in 9.2 x 1013 molecules of water?

Whiteboard Practice How many moles are in 726 grams of Mercury?

Whiteboard Practice How many atoms are in 23.7 g of Cobalt?

Whiteboard Practice How many grams are in 2.11 x 1042 atoms of Xenon?

Whiteboard Practice What is the difference between a homogenous and heterogenous mixture?

Whiteboard Practice Give an example of an element, a compound, and a mixture.

Exit Ticket 3 – What are three things you have learned about elements this unit? 2 – What are two things that you want more practice with? 1 – What is one thing question you have? Finally, rate your confidence in drawing Bohr models now, after today’s practice, using the same scale as the beginning of class.
