REVIEW QUESTIONS
Section 1
1. What meaning did the Greek word “atomos” have?
2. Know definitions:
a. Atom
c. Nucleus
b. Electron
c. Electron cloud
3. Who discovered the electron?
4. What else did discovering the electron tell this person about atoms?
5. Who discovered that atoms are mostly empty space with a small but dense positive center?
6. What is the modern (current) model of an atom?
7. Know scientists’ theories (big ideas) on atoms, their “model” (how they pictured atoms), and
how they developed ideas (was there a famous experiment? Other ways mentioned?)
TIME
PERIOD
Democritus
Dalton
Thomson
Rutherford
Bohr
Schrodinger and
Heisenberg
THEORY (Main ideas)
MODEL
HOW
Section 2
8. Know definitions of vocab words: (1) proton, (2) atomic number, (3) isotope, (4) atomic mass
unit, (5) mass number, (6) neutron, (7) atomic mass, and (8) ion.
9. What are the three subatomic particles of an atom?
10. Draw a sketch of an atom below that has 3 protons, 3 neutrons, and 3 electrons.
11. What element would the atom you drew in # 10 be? (see the Periodic Table in your book on
page 570) EXPLAIN HOW YOU KNOW!
12. If you were given a periodic table, how could you figure out how many protons an atom of
Nickel has?
13. Atoms of the SAME ELEMENT always have the SAME NUMBER OF ________________.
The two ways that atoms of the SAME ELEMENT can be different are if the number of
_______________________ changes (then it is called an ___________________) or the
number of _________________________ changes (this is called an __________________).
14. What has the MOST MASS in an atom? What unit do we use to measure this?
15. Why are most atoms neutral (they have no charge as a whole particle)?
16. What force keeps the electrons moving around the nucleus of its atom?
17. What force keeps the nucleus together?
18. How can you find the mass number of an isotope? (see page 555- two ways possibly)
19. If an atom has 38 protons, 64 neutrons, and 38 electrons, what is its mass number?
Study your vocabulary list, 20-2 guided notes, 20-1 Quiz (and Personal Study Guide), the Chapter Review
Packet, Directed Readings, Review WS’s and book.
