Describe Thomson model of an atom which sub atom particle was not present in Thomson model of atom
Answers
Answer:
according to Thomson atom is made up of positive sphere in which electrons are embedded. he compared it with watermelon where seeds are as electrons
Question :-
Describe Thomson's model of the atom. Which subatomic particle was not present in Thomson model of the atom ?
Answer :-
Thomson's Model of Atom :
⬛ Thomson's model of the atom was the first model.
⬛ He said that atom is a sphere of positive charge.
⬛ According to him, electrons (negative charges) were embedded in the positive sphere.
⬛ He compared an atom to a Christmas pudding.
⬛ The pudding was said to be the positive sphere of the atom and the dry fruits in it was compared to the negative charges or the electrons.
⬛ We can also compare this mod of an atom with a watermelon.
⬛ The red part part of the watermelon can be said the positive sphere.
⬛ Whereas, the seeds of the watermelon embedded allover the red part can be said to be the electrons.
He concluded with result as:
⚫An atom is a positive sphere embedded with electrons.
⚫The magnitude of positive charges and negative charges are equal, making an atom electrically neutral.
➡ The subatomic particle was not present in Thomson Model : Neutrons.
