Who proposed the plum-pudding model of the atom?
J J Thomson
When was the Jj.Thompson model discovered?
Joseph John Thomson proposed his plum pudding model Of atom in the year of 1904.
What was the name of the concept model that Thomson proposed based on his experiments?
JJ Thomson called his model of the atom the plum pudding model.
In Thomson's plum pudding model the mass of the atom is in the?
In Thomson's plum pudding model, the mass of the atom is spread out uniformly throughout the positively charged sphere, similar to plums in a pudding. This model proposed that electrons were embedded in the positive sphere like plums in the pudding, representing the negative charges.
Which scientist first made a model of the atom called the plum pudding model?
J.J. Thomson, a British physicist, first proposed the plum pudding model of the atom in 1904. This model described the atom as a positively charged sphere with electrons embedded in it, similar to the seeds in a plum pudding.
According to the Plum Pudding Model electrons are distributed randomly throughout the positively charged pudding of the atom?
The Plum Pudding Model proposed by J.J. Thomson depicts electrons as dispersed throughout a positively charged atom, much like plums in a pudding. This model suggested that the atom is overall electrically neutral due to the balance of positive and negative charges. However, this model was later replaced by the Rutherford model which proposed a nucleus at the center of the atom surrounded by orbiting electrons.
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.
What changes did Thompson and Rutherford make?
Thompson discovered the electron and proposed his "Plum Pudding" model of the atom, while Rutherford refined it, moving the electrons to shells outside the nucleus. Google "Rutherford Model" and "Plum Pudding Model" for more info
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.
What is JJ Thomson model called?
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.
What is the difference between the plim pudding model and the nuclear model?
The "plum pudding" (as they called it) model suggest's that the electrons were dispersed throughout the atom. Where as the nuclear model has positively charged protons which are present in the center of an atom (called the nucleus)
What was Crookes atomic model called?
The Crookes atomic model is known as the plum pudding model. It was proposed by Sir William Crookes in 1904 and suggested that atoms are composed of a positively charged "pudding" with embedded negatively charged electrons.
