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.
Which atomic model was proposed as a result of j.j. Thomsons work?
J.J. Thomson's work led to the proposal of the "plum pudding model" of the atom in 1904. In this model, the atom is envisioned as a spherical cloud of positive charge with negatively charged electrons embedded within it, similar to plums in a pudding. This model was an early attempt to describe the internal structure of the atom before the discovery of the nucleus and the later development of the Rutherford and Bohr models.
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.
Which atomic model was proposed as a result of j j thomsons work?
J.J. Thomson's work led to the development of the "plum pudding model" of the atom. In this model, atoms were envisioned as a positively charged "soup" in which negatively charged electrons were embedded like plums in a pudding. This model suggested that the atom was a uniform sphere of positive charge with electrons scattered throughout, providing an early understanding of atomic structure before the discovery of the nucleus.
Which event came first- plum pudding modelgold foil experiment cathode ray tube exp discovery of nucleus discovery of electrons?
The cathode ray tube experiment came first, conducted by J.J. Thomson in the late 1890s, leading to the discovery of electrons. This was followed by Thomson's plum pudding model in 1904. The gold foil experiment, performed by Ernest Rutherford in 1909, led to the discovery of the nucleus.
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 atomic model was proposed as a result of j j thomsons work?
J.J. Thomson's work led to the development of the "plum pudding model" of the atom. In this model, atoms were envisioned as a positively charged "soup" in which negatively charged electrons were embedded like plums in a pudding.

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.
