The plum pudding model of the atom was not correct. The prediction that alpha particles would pass through a sample of matter and would be deflected only minimally was disproved by rutherford and co-workers who found that some alpha particles (1 in 8000) bounced almost straight back. This was explained by the presence of a nucleus.
Other phenomena were also difficult to explain. For example atomic absorption spectra with the sharp, principal and diffuse lines.

What was Thomson's model of the atomic atom?
according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
What were J. J. thomsons ideas called?
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
How is Tho masons model different from Daltons?
Thomsons model (plum pudding model of negatively charged particles in a positive soup) differed from Daltons model. Dalton hypothesised that atoms were indivisible, the word atom comes from the Greek atomos cannot be cut)
How did Thomson's' experiment change Dalton's atomic model?
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
What was JJ Thomsons 1904 model called?
The model was called the: The Plum Pudding Model
What was JJ Thomsons model of the atom called?
plum pudding model

J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
How did Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
How is Tho masons model different from Daltons?
Thomsons model (plum pudding model of negatively charged particles in a positive soup) differed from Daltons model. Dalton hypothesised that atoms were indivisible, the word atom comes from the Greek atomos cannot be cut)
What is the difference between Thomsons atomic model and Rutherfords atomic model?
Thomson's model was the "Plum Pudding model" because it had electrons "floating" around in the ball, but Rutherford's model shows the electron shells, the nucleus, and the molecular particles: neutron, proton, and electron. Hope this helps!
What scientific inquiry skill was Rutherford using in selecting Thomson's model for investigation?
Thomsons model is sometimes called the plum pudding model. Rutherfords results that while most alpha particles were undeflected some alpha particles bounced back
Did Ernest Rutherfords results fit with J.J Thomsons view of the atom?
Thomsons model is sometimes called the plum pudding model as he envisaged a soup of positive charge with negative charges, by then already called electrons swimming round. He came up with this idea in 1904."the atoms of the elements consist of a number of negatively electrified corpuscles enclosed in a sphere of uniform positive electrification"Rutherford following on from the famous scattering experiment with gold foil and alpha particles proposed that the positive charge was concentrated in a central nucleus.
How did Thomson's' experiment change Dalton's atomic model?
An atomic model of Dalton doesn't exist; the model of Thomson was called plum pudding model.
What is the purpose of the Rutherford experiment?
he wanted to test Thomsons model maybe
How did Rutherfords model of the atom different from thomsons?
The Rutherford model involve a positive nucleus separated from electrons.
