A chemical reaction results in the rearrangement of atoms in the reactant and product compounds. Share this: Twitter Facebook.

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. Dalton and Thomson's atomic models J. Some nicknames for this model are "plum pudding" and "raisin bread". The Plum Pudding Model is a model of atomic structure proposed by 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. How is Thomson's model of an atom different from Dalton's model? Himanshu Shekhar. Nov 2, Explanation: John Dalton proposed that all matter is composed of very small things which he called atoms.
