**This was made to help you review topics we have discussed in this chapter**
Model the parts of the atom.
1) Draw and describe the model of the atom for the following scientists.
Scientist
Dalton
J.J. Thomson
Rutherford
Bohr
Chadwick
Drawing of Model
Description
Explain the differences between protons, electrons, and neutrons.
2) Complete the table below then use the diagram to compare and contrast the subatomic particles.
Protons
Neutrons
Charge
Location
Relative Mass
Electrons
3) What two subatomic particles are responsible for the mass of the atom?
Electrons
4) What are isotopes? How do you know if an atom is an isotope of another atom?
5) Use the following diagram of 3 nuclei (of the same element) to fill in the table below:
C
B
A
a) What element is this?_____________________________________
Model A
Model B
Model C
Number of Protons
Number of Neutrons
Number of electrons
Mass of each
Explain the role of valence electrons and where to find them.
6) What are valence electrons?
7) Why are they significant?
Predict the properties of an element based on its location on the periodic table including metals,
nonmetals, and metalloids.
8) Name 2 elements in the Nobel Gas Family. What is there reactivity and why?
9) Why are there only 2 elements in the first period on the periodic table? Why are they on
opposite ends of the periodic table?

12) Describe the reactivity trend as you move down a group on the periodic table.
Represent the atom of an element by drawing a Bohr model and Electron Dot Structure (Lewis
Structure) of that atom
14) What information does a Bohr model give you that Lewis Dot does not?
