ThomsonC

[] J.J Thomson 1) This is an image of J.J. Thomson's version of the atom called the "Plum Pudding Model" It was proposed in 1904.

2) We did not find any specific experiments that led to this discovery, but we did find that the discovery of the electron(discovered by Thomson) lead to his creation oft his model.

3). Thomson’s plum pudding model could not account for the fact that in rutherfords expiriments alpha particle were deflected nearly 90 degrees in some cases, proving that there is a central, positively charged, nucleus.

Short comings: This model doesn't really represent anything about neutrons, and neutrons are very important in the stability of an atom.

Interesting Facts: -Won the nobel prize in 1906 -Knighted in 1908 -Real Name: Joseph John Thomson -Discovered the electron

His Experiment: -Called it the plum pudding model because electrons in a sphere of a positive charge were situated like plums in a pudding. -Came to the conclusion that each and every atom consisted of homogenous sphere of positive electricity. inside of the sphere negative electrons were to rotate on some orbits round the spheres center
