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 are the differences between the plum pudding and planetary models of the atom?
The plum pudding model describes the atom as a pudding, occupying most of the volume an atom occupies. The pudding is positively charged. Inside the large pudding are negatively charged specs (plums), representing electrons. This model was found to be flawed because, when alpha particles were fired at atoms, it was found that a proportion of the positively charged alpha particles consisting of two neutrons and two protons backscattered. This meant that the positive charge density (charge per unit volume) of the atom must have been greater than what was described by the plum pudding model. For this to make sense, most of the atom must actually have been a vacuum. Therefore, the planetary model was created to describe atom more accurately. In the planetary model (nuclear model), the atom consists of electrons orbiting a nucleus. The nucleus consists of protons and neutrons.
How did the model of the atom affect scientific thought?
scientist accepted bohr's model as a useful explanation (apex)
What J J Thomson was famous for?
he was a British scientists that discovered negatively charged particles, electrons, inside the atom. he proposed a possible structure of the atom (atomic model) called the plum pudding. you can google some images

Erwin Schrodinger
What scientist atomic model was called the plum pudding model or the chocolate chip cookie dough model?
Joseph John Thomson
What was Thompson's model of the atom called?
its called the plum pudding model
What was JJ Thomsons 1904 model called?
The model was called the: The Plum Pudding Model
Which scientist developed plum pudding model?
The plum pudding model of the atom was put forward by J.J. Thomson.
What was Thomson's model atom called?
The name was plum pudding.
What scientist is associated with the plum pudding model of the atom?
J. J. Thompson.
Which scientist or scientists came up with the Electron Cloud nodel of the atom?
I think you're referring to JJ Thomson's model. It is more oftenly called the 'plum-pudding model'.
What did JJ Thompsom contribute to the development of the periodic table?
JJ Thomsan was the first scientist to propose the structure of atom.He gave plum pudding model.
What was Thomson's model of atom called?
The name was plum pudding.
What was JJ Thomsons model of the atom called?
plum pudding model
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.
