Which of the following statements about Thomson's model of an atom is INCORRECT?
1
The negative and positive charges are not equal in magnitude. So, the atom as a whole is not electrically neutral.
2
The positive charge in the atom is spread all over like the red edible part of a watermelon, while the electrons are studded in the positively charged sphere, like the seeds in the watermelon.
3
The negative and positive charges are equal in magnitude. So, the atom as a whole is electrically neutral.
4
An atom consists of a positively charged sphere and the electrons are embedded in it.
