Question

how was the atom proposed by thomas different from the atom proposed by dalton

Answer 1

****Heyy friend here is ur answer****

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. He thought atoms to be literally 'a tomos' meaning 'uncuttable'

Later JJ Thompson using his Cathode ray tube experimented and found out that atoms were made up of different charged particles. This he called the plum pudding model. The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century.

Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom. He therefore proposed that atoms have structure similar to a plum pudding, with tiny, negatively charged electrons embedded in a positively charged substrate. This was later shown to be incorrect.

Hope it was helpful:-)

Answer 2

Answer:

Dalton and Thomson's atomic models:-

J.J Thomson's atomic model was a sphere embedded with electrons. The sphere had positive positive charges throughout it and negatively charged particles were also scattered across this model.

Some nicknames for this model are "plum pudding" and "raisin bread".

Thomson proposed the most primitive model in 1898.

Thomson thought of this "plum pudding" idea after he discovered the electron, before that he believed it was just a small sphere.

Dalton's model explained that atoms were tiny invisibly, indestructable particles; And that each had a certain mass, size, and chemical behavior that determined by what kind of element they were. He called his model the " Billiard Ball model" because he thought that atoms looked like billiard balls from pool. John Dalton theorized that matter was made up of many tiny particles called atoms that had no parts. And he thought that atoms looked like Billiard Balls.
