Question

thomson model of an atom

Answer 1

The 'plum pudding' model of the atom was proposed by JJ Thomson, who had also discovered the electron. It was put forth before the discovery of the nucleus. According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

Answer 2

Thomas model of atom :-

➡️The main features of Thomson’s model of atom are:✔️

➡️Atom consists of a positively charged sphere✔️

➡️Electrons are embedded in atoms
Negative and positive charges are equal in magnitude✔️

➡️Atom as a whole is electrically neutral✔️


➡️This model was explained with the help of a watermelon wherein the red edible part resembles positive charge in the atom and the black seeds resemble the electrons embedded in positive sphere.✔️

➡️This model is also known as plum pudding model✔️

➡️The limitation of this model is that it was not able to explain the results of the experiments obtained by other scientists like Ernest Rutherford.✔️
