Atomic Theory

Question 11 • GA-GSE Physical Science A

Which statement describes one feature of Rutherford’s model of the atom?

Answer
A
The atom is mostly empty space.
B
The atom cannot be divided into smaller particles.
C
Electron clouds are regions where electrons are likely to be found.
D
The electrons are located within the positive material of the nucleus.

Explanation

Rutherford’s gold-foil experiment showed that most alpha particles passed through the foil, suggesting that atoms are mostly empty space. A few particles were deflected by a small, dense, positively charged nucleus. Thus, “The atom is mostly empty space” describes Rutherford’s model; electron clouds are part of a later model.
