Question

One of the earliest atomic models was suggested by John Dalton in the early 1800s.

Which statement best reflects his thinking at the time?

A. Atoms can be divided into small parts.
B. Smaller particles are found inside atoms.
C. All atoms are exactly the same.
D. Atoms are like solid little balls.

Answer 1

D. Atoms are like solid balls

Step-by-step explanation:

John Dalton proposed that all matter is composed of very small things which he called atoms. This was not a completely new concept as the ancient Greeks (notably Democritus) had proposed that all matter is composed of small, indivisible (cannot be divided) objects. When Dalton proposed his model electrons and the nucleus were unknown.
