Question

Soren is making a poster about John Dalton’s understanding of the atom. Which of these statements would Soren leave off his poster as it was not a part of Dalton’s atomic theory?

a) Atoms are made up of smaller particles.
b) All atoms of the same element are identical.
c) Atoms of different elements are different and have different masses.
d) Compounds form when atoms of different elements combine in a specific ratio.

Answer 1

Soren should not include the statement 'Atoms are made up of smaller particles' on the poster about Dalton's atomic theory, as it contradicts the theory's postulate that atoms are indivisible.

Step-by-step explanation:

When creating a poster about John Dalton's understanding of the atom, the statement that Soren should leave off as it was not a part of Dalton's atomic theory is: a) Atoms are made up of smaller particles. Dalton's atomic theory posited that atoms are indivisible and cannot be subdivided into smaller particles.

This is one of the central ideas of his theory, which was later disproved with the discovery of subatomic particles like protons, neutrons, and electrons.

The other options b) All atoms of the same element are identical, c) Atoms of different elements are different and have different masses, and d) Compounds form when atoms of different elements combine in a specific ratio, are all consistent with Dalton's theory.
