Question

write the difference between delton , Thomsan and Ruther Ford's atomic structure ..​

Answer 1

From this he decided that these particles must have come from somewhere within the atom and that Dalton was incorrect in stating that atoms cannot be divided into smaller pieces. Thomson went one step further and determined that these negatively charged electrons needed something positive to balance them out.

Answer 2

Answer:

The difference between Thomson's model of the atom and Rutherford's model was that Thomson's model had atoms that have smaller particles called electrons and Rutherford's model had electrons move about a nucleus.

Thomson's theory included the atoms having electrons, while Rutherford's said that atoms have a nucleus and electrons orbit the nucleus. the two differences are where the electrons ARE and nucleus or no-nucleus.In his model the electrons are scattered throughout a ball of positive charge.

From this he decided that these particles must have come from somewhere within the atom and that Dalton was incorrect in stating that atoms cannot be divided into smaller pieces. Thomson went one step further and determined that these negatively charged electrons needed something positive to balance them out.

Now, let's fast-forward to the late 1800s when J.J. Thomson discovered the electron. Thomson used what was called a cathode ray tube, or an electron gun. You've probably seen a cathode ray tube without even knowing it! They are the bulky electronic part of old television sets. Thomson used the cathode ray tube with a magnet and discovered that the green beam it produced was made up of negatively charged material. He performed many experiments and found that the mass of one of these particles was almost 2,000 times lighter than a hydrogen atom. From this he decided that these particles must have come from somewhere within the atom and that Dalton was incorrect in stating that atoms cannot be divided into smaller pieces. Thomson went one step further and determined that these negatively charged electrons needed something positive to balance them out. So, he determined that they were surrounded by positively-charged material. This became known as the 'plum pudding' model of the atom. The negatively charged plums were surrounded by positively charged pudding.
