J.J. Thomson, also known for discovering the electron, also proposed a model of the atom in 1904. This model is known as both the plum pudding model and the blueberry muffin model, and it posits that the atom is made up of electrons which are surrounded by a "pudding" of positive charges.
it was electrons
JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.
J.J. Thomson performed his experiment to discover the existence of subatomic particles known as electrons. By studying the properties of cathode rays, he was able to determine the charge-to-mass ratio of electrons and propose the plum pudding model of the atom.
J. J. Thomson's scientific ideas were called the "plum pudding model" or the "Thomson model." This model proposed that atoms were composed of a positively charged material with negatively charged electrons embedded within it, resembling plums in a pudding.
J. J. Thomson's ideas are called the "plum pudding model" of the atom, which proposed that atoms are composed of positively charged material with negatively charged electrons embedded within it. This model was later replaced by the more accurate "nuclear model" proposed by Rutherford.
JJ Thomson called his model of the atom the plum pudding model.
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.
Joseph John Thomson or (JJ Thomson)
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.
The plum pudding model by JJ Thomson.
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.
JJ Thomson
The evidence for JJ Thomson was that the plum pudding model could not predict why atoms absorbed and emitted spectral lines.
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
One drawback of JJ Thomson's atomic model was that it could not explain the distribution of positive charge within the atom. Additionally, it could not account for the stability of atoms with multiple electrons. Ultimately, Thomson's model was replaced by the more accurate and comprehensive model proposed by Ernest Rutherford.
I'm pretty sure it was jj. Thompson but i coudnt be sure
