* Atoms are positively charged sphere and electrons are embedded in it.

* The negative and positive charges arevequalmin magnitude so that the atoms are overall neutral.

Answer 2

Answer :

Thomson's Model of Atom :-

• J.J. Thomson proposed a model of atom in 1898.
• According to him, an atom is a spherical shape of about 10^{-10} m radius.
• Positive charge is uniformly distributed in the atom.
• The are embedded in this positive charged spherical.
• They are embedded in such a manner that the atom is electrostatically stable.
• This model of atom is also called plum pudding, raisin pudding or watermelon.
• He visualized atom as a pudding or watermelon in which seeds aur plums are embedded like electrons.
• According to J.J. Thomson, mass of the atom is uniformly distributed over the atom.
• It was first model of atom introduced by someone.
• However, it wasn't correct model.
• It did not show how an atom is neutral.
