question 6 of 10
which of the following ideas did john dalton teach?

a. that matter was made up of mostly space
b. that mass and energy were related
c. that matter was made of indivisible particles
d. that atoms contained smaller particles

Explanation:

John Dalton's atomic theory proposed that matter is composed of indivisible particles called atoms. Option A (matter mostly space) relates to later atomic models like Rutherford's. Option B (mass - energy relation) is Einstein's $E = mc^2$. Option D (atoms with smaller particles) was discovered after Dalton, as Dalton thought atoms were indivisible. So the correct idea taught by Dalton is that matter was made of indivisible particles.

Answer:

C. That matter was made of indivisible particles
