Honors Chemistry 1 Atomic Theory Quiz Review/Practice Quiz
1.
Name Each Scientist from the Greek philosophers to Bohr. Describe their models, draw a picture,
and how their experiment proved their point by specifying what properties were being measured.
2.
Balance: AgCl + Na2SO4  Ag2SO4 + NaCl and explain why it must be balanced
3.
What are Dalton’s three points for his atomic theory? Are they all currently true? Explain.
4.
What are the three classic subatomic particles? List each respective charge, location, and mass?
5.
What is an element’s atomic number? mass number? What does the atomic mass tell you?
6.
What is an isotope? How is an element’s mass number different from its atomic mass? Write the
Isotope notation for an element with the atomic number 6 and a mass number of 14. How many
neutrons does this isotope have?
7.
Explain why an atom’s atomic mass can be different from each isotope:
8.
What is the atomic mass of Copper with isotopes Cu-63 (mass of 63.0 amu and 69.2% abundance)
and Cu-65 (mass 65.0 amu and 30.8% abundance)? Do the equation including units with sig figs.
9.
Lithium has an atomic Mass of 6.94 amu. What is the percent abundance of the two isotopes (Li 6
and Li 7) that make up Lithium?
10.
What is the relationship between frequency, wavelength, energy and speed?
11.
List the order of electromagnetic waves from lowest to highest wavelengths
12.
Which color of light has the highest frequency? Lowest frequency?
13. What evidence told scientists that electrons were located on specific energy levels, rather than
being scattered randomly around the nucleus?
14. An atom emits 3 colors of light, Red, Yellow and Violet when excited by an E.M. wave. Draw the
Bohr Model of an atom that shows these colors of light being emitted.
15.
