J.J. Thomson proposed that an atom consists of a mixture of positively charged protons and negatively charged electrons. In his model, the electrons can be thought of as tiny marbles suspended in a "pudding" made up of protons.

Niels Bohr found this model to be incorrect, and instead described the atom more accurately as a sort of planetary configuration. In his model, electrons orbit the nucleus which consists of the protons.

Bohr's model was backed up experimentally by Ernest Rutherford's work.

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.


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 did JJ Thomson call his model of the atom?

JJ Thomson called his model of the atom the "plum pudding model." In this model, electrons were embedded in a positively charged sphere, resembling the distribution of plums within a British pudding dessert.


What particle did J. J. Thomson discover?

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 discovery lead the scientists to question john daltons model of the atom and to favor jj Thomsons model?

The discovery of the electron by J.J. Thomson through his cathode ray tube experiment led scientists to question John Dalton's model of the atom. Thomson's observation of negatively charged particles in the cathode ray, along with their behavior under electric and magnetic fields, contradicted Dalton's indivisible and uniformly dense model of the atom. Thomson's model, proposing that atoms contain subatomic particles (electrons), gained favor due to its ability to explain these experimental findings.
