1. Watch “Reading the Periodic Table” first – then do questions 1-9.
2. Watch “Counting Subatomic Particles” (1st 10:05 only) while doing the remainder of the
questions.
1. What are the three main "ingredients" of all atoms?

2. The ___________ is the center of the atom.
A. Proton
B. Neutron
C. Electron
D. Nucleus
2. What is a proton?
A. A negatively charged particle in the nucleus
B. A particle in the nucleus with no charge
C. A particle outside of the nucleus with a positive charge

C. Found on the Periodic Table
D. 2 or more of the above are true
E. None of the above are true
9. What part of the atom is the arrow pointing to?
A. Electron
B. Proton
C. Neutron
D. Nucleus
E. None of the above are true
Go to our class blog http://parade78stem.edublogs.org/ and watch the first 10:05 minutes of
the video “Counting Subatomic Particles” while filling out this assignment.

14. How do we calculate the average atomic mass?
A. Add them up and divide by two.
B. To calculate the average atomic mass, multiply the fraction by the mass number for each isotope,
then add them together.
C. None of the above.
15. The _______________ is always a whole number.
A. Atomic number
