Question 19 • IA-Chemistry A Survey of Chemistry A

Which is a component of John Dalton’s atomic theory?

Answer
A
The ratio of atoms in a compound can vary.
B
The atoms of a single element differ.
C
An atom is a small particle that cannot be broken down.
D
Atoms of different elements can be identical.

Explanation

Dalton’s atomic theory described atoms as tiny, indivisible particles that make up matter. Therefore, the component is that an atom is a small particle that cannot be broken down. Dalton also held that atoms of the same element are alike and that compounds have fixed ratios of atoms, so the other statements do not fit his theory.
