**Green**,

**Yellow**, or

**Red**today? Ask yourself, "Am I able to do the following?":

- Convert between moles, grams, and atoms.

- Describe the importance/"role" of the proton, neutron, and electron.
- Describe and identify isotopes.
- Calculate average atomic mass using percent abundance data.
- Write isotopes in BOTH hyphen notation and nuclear symbol notation.
- Write electron configurations.

**Reflection #6: 10/23 & 10/24**

Are you

**Green**,

**Yellow**, or

**Red**today? Ask yourself, "Am I able to do the following?":

- Describe a mole. What is it? What is it equal to?
- How do I rewrite a conversion factor as a "fraction"?
- Use dimensional analysis to convert between units. Do I know the basic setup? What value do I always start with? What unit(s) must go in the denominator of a conversion factor?
- How do I determine the number of sig figs for my final answer?

**Reflection #5: 10/19 & 10/22**

## Unit 2: Measurements

**Reflection #4: 10/15 & 10/16**

__Unit 2 Checklist__

Are you

**Green**,

**Yellow**, or

**Red**today? Ask yourself, "Am I able to do the following?":

- Take proper measurements with the correct number of digits.
- Perform metric conversions (kilo, base, centi, and milli).
- Interpret graphs (scatter vs. bar, direct vs. inverse, IV on x-axis, DV on y-axis).
- Explain the differnce between accuracy and precision.
- Calculate percent error (know the formula and how to calcualte correctly).

**Green**,

**Yellow**, or

**Red**today? Ask yourself, "Am I able to do the following?":

- Count/identify signifcant figures in a measurement.
