Question

JJ Thomson model of atom

Answer 1

Answer:

Thomson proposed the model of an atom to be similar to that of a Christmas pudding and watermelon, the positive charge in the atom is spread all over like the red edible part of the watermelon, while the electrons are studded in the positively charged sphere, like the seeds in the watermelon.

Observation :

1. An atom consists of a positively charged sphere and the electrons are embedded in it

2. The negative and positive charges are equal in magnitude. So, the atom as a whole is electrically neutral.

Result :

1. Thomson's model explained that atoms are electrically neutral

Failure :

1.The results of experiments carried out by other scientists could not be explained by this model

Answer 2

Answer:

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."
