LEARNING GOAL: Students will be able to read and answer questions when atoms are in shorthand notation, Convert between units and solve problems involving molar relationships by working in groups to complete practice problems. 

ICEBREAKER: 1. Take about 5 minutes to create a name tag that you will use for the remainder of the quarter, this will be used to also write any random questions that you have throughout the tutorial session, whether it be about the material or the class itself.

Guided Practice: 1. What do the symbols A , Z and X represent in terms of shorthand notation?   2. How do you keep track of significant figures when adding or subtracting? dividing or multiplying?   3. Define Isotopes and how they are measured in nature. 1 

  4. Mole Relationship:  

Group Practice: Write isotopic symbols in the form AZX for each isotope. a. the copper isotope with 34 neutrons b. the copper isotope with 36 neutrons  Determine the number of protons and the number of neutrons in each isotope. a. 40,19 K b. 226,88 Ra  Perform each unit conversion. a. 28.9 nm to µm b. 1432 cm3 to L c. 1211 Tm to Gm  How many moles of aluminum do 3.7 * 1024 aluminum atoms represent?  

2 

Independent Practice: Determine the number of protons and the number of electrons in each ion. a. Al3+ b. Se2-  What is the mass of 4.91 * 1021 platinum atoms?  What is the mass, in grams, of each elemental sample? a. 2.3 * 10-3 mol Sb b. 0.0355 mol Ba

ACTIVITY Write down any questions you still have and post them to the discussion board on canvas to allow fellow students to answer them.
