Answer 1

Answer:

J.J. Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons.

Thomson's plum pudding model of the atom had negatively-charged electrons embedded within a positively-charged "soup."

Answer 2

Answer:he used christmas puding in his experiment.

tHe electron in sphere of positive charge were like currants in a spherical pudding. thomson proposed that:

Explanation:1.an atom consist of a positively charge sphere and the electron are embedded in it.

2.the negative and positive charge are equal in magnitude.so,the atom as a whole is electrically neutral.
