Chemistry Review Challenge
Directions: Your group will work together using any resources available in the room to answer the questions
below. (Note: I would highly suggest using the blue matter books as one of those resources…but it’s up to
you!…good luck with your decision)
Rules:
1. You must get your answers checked for each section BEFORE moving on to the next section!
2. All questions from each section must be done to perfection before moving on to the next section!
3. All group members need to come get answers checked
4. All group members must be able to explain HOW you got your answer if asked…we are shooting for all to
understand the material! 
5. All group members must fill out their own sheets with the correct answers (this will become notes)
Good Luck with your challenge!

Atomic Structure
1.The 3 particles that make up an atom are:
a.______________________
b.______________________
c.______________________
Their respective charges are:
a.______________________
b.______________________
c.______________________
2.The atomic number tells you the number of ______________________in one atom of an element. It also tells you
the number of _____________________in a neutral atom of that element. The atomic number gives the “identity “
of an element as well as its location on the Periodic Table. No two different elements will have the __________
atomic number.
3.The ______________________of an element is the average mass of an element ’s naturally occurring atom, or
isotopes, taking into account the ______________________of each isotope.
4.The ____________________of an element is the total number of protons and neutrons in the _______________ of
the atom.
5.The mass number is used to calculate the number of ______________________in one atom of an element. In
order to calculate the number of neutrons you must subtract the ___________________from the
______________________.
