J.J. Thomson reported his plum pudding model of the atom in 1904, proposing that atoms were composed of a positively charged "soup" with negatively charged electrons embedded within it. The reaction was mixed; while it was a groundbreaking step in atomic theory, it faced skepticism and criticism from other scientists, particularly as more advanced models emerged later on, such as Ernest Rutherford's nuclear model of the atom in 1911.
What else can I help you with?
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.
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.
His theory of atomic structures led to the plum pudding model?
The plum pudding model was proposed by J.J. Thomson in 1904, before the discovery of the atomic nucleus. It suggested that atoms were composed of positively charged substance with electrons embedded within it like plums in a pudding. It was later replaced by the Rutherford model when the nucleus was discovered.
In the plum pudding experiment electrons are mixed throughout what?
In the plum pudding model, electrons are mixed throughout a positively charged "pudding" of uniform density. The model was proposed by J.J. Thomson to describe the structure of the atom before the discovery of the nucleus.
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 Rutherfords findings change Thomsons plum pudding model?
Rutherford supposed that the atom had a central positive nucleus surrounded by negative electrons.
What was JJ Thomsons 1904 model called?
JJ Thomson's 1904 model was called the "plum pudding model." This model described the atom as a sphere of positive charge with electrons embedded throughout, like plums in a pudding. It was later replaced by the more accurate Rutherford model.

What was JJ Thomsons model of the atom called?
JJ Thomson's model of the atom is called the "plum pudding model." It suggested that atoms were made up of positive and negative charges distributed throughout a neutral, positively-charged background.
Which item best represents thomsons mental image of an atom?
The plum pudding model best represents J.J. Thomson's mental image of an atom. In this model, electrons are embedded within a positively charged "pudding," similar to how seeds are embedded in a watermelon.
What did J. J. Thomsons experiments provided evidence about an atom?
J. J. Thomson's experiments provided evidence for the existence of electrons as subatomic particles within the atom. This led to the plum pudding model of the atom, where electrons were embedded in a positively charged "pudding." These experiments laid the foundation for our understanding of atomic structure.

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.
