Chemistry Unit Test Study Guide
***To prepare for the test, you must study your notes and past quizzes as well. ***
Directions: Use your Chemistry Part 1, 2 & 3 Notes to complete this review.
Part 1:
1.
Matching:
Rutherford
Bohr
Dalton
Thomson
Modern (Quantum) Theory
_______________ believed the atom was a solid sphere with no charges
_______________ theorized that the atom looked like Plum Pudding (positive sphere with negatives
sprinkled throughout)
_______________ believed that the atom had a positive nucleus with electrons surrounding it. The
Gold Foil Experiment was the basis for his theory.
_______________ believed the atom had a nucleus containing protons and neutrons, and that the
electrons were in fixed energy shells around the nucleus.
_______________ the current theory of the atom – the atom has a nucleus containing protons and
neutrons, and the electrons are in a cloud around the nucleus.
