Johnston: Essentials of Radiographic Physics and Imaging, 2nd Edition
MULTIPLE CHOICE
1. The earliest atomic theory is generally associated with
a. Bohr
b. Leucippus
c. Democritus
d. Dalton
ANS: B
Although his theory was somewhat vague, Leucippus is most often the earliest person
associated with atomic theory.
REF: 16 OBJ: 1
2. The word atom is derived from the Greek word atomos, meaning
a. nuclear
b. small
c. indivisible
d. invisible
ANS: C
The Greek word atomos means “indivisible.”

a. elements form compounds
b. atoms are unique to each element in size and mass
c. a chemical reaction results from atoms being rearranged
d. all of the above
ANS: D
As a result of his experiments, John Dalton theorized that elements form compounds, atoms
are unique to each element in size and mass, and that a chemical reaction results from atoms
being rearranged.
REF: 16 OBJ: 1

a. Dalton
b. Bohr
c. Thomson
d. Rutherford
ANS: C
Joseph John “J.J.” Thomson determined that the electron was a negatively charged part of the

5. The “plum pudding model” is associated with
a. Bohr
b. Rutherford
c. Dalton
d. Thomson
ANS: D

and surrounding negatively charged particles (electrons).
REF: 17 OBJ: 1
6. The earliest atomic theory based on an arrangement similar to the solar system is attributed to
a. Bohr
b. Rutherford
c. Dalton
d. Thomson
ANS: B
Rutherford developed the theory that the atom consisted of a very dense nucleus with small
electrons rotating around, similar to the sun and planets.
REF: 17 OBJ: 1
7. The most commonly known modern atomic theory was developed by
a. Bohr
b. Rutherford
c. Dalton
d. Thomson
ANS: A
Niels Bohr refined Rutherford’s atomic theory, based on the solar system, into the most
commonly known atomic theory today.
REF: 18 OBJ: 1
