What are the differences between Dalton's model of the atom and Thompson's model of the atom?

Answer 1

Dalton never acknowledged the fact that the atomic structure consisted of protons nor electrons. Dalton's theory suggested:

unlike Thomson who came up with the theory of the 'Plum Pudding Model', which consisted of a positive proton with electrons 'scattered' through it, like "...currants in a Christmas pudding..."

hope this was somewhat helpful :)

1. Matter is made up of indivisible atoms.
2. All atoms of an element are identical.
3. Atoms are neither created nor destroyed.
4. Atoms of different elements have different weights and chemical properties.
5. Atoms of different elements combine in simple whole numbers to form compounds.

Answer 2

Dalton's model viewed atoms as indivisible particles with unique mass, while Thompson's model proposed atoms as containing negatively charged electrons embedded within a positively charged sphere. Dalton's model did not account for subatomic particles, while Thompson's model introduced the concept of electrons as constituents of the atom.

Answer 3

Dalton's atomic theory postulated that atoms were indivisible. JJ Thomson's model showed that atoms were divisible into negatively charged electrons.

Answer 4

John Dalton is not author of a model of the atom.
