Thomsons atomic theory proved that the stream in cathode ray tube is made of small particles which is piece of the atom and is

• Neutral

• Negatively charged

• Positively charged

• Both negative and positively charged

Thomsons atomic model is also known as

• Water melon model

• Raisin pudding model

• Plum pudding model

• All of the above

Thomsons atomic model suggested that atom is

• Divisible

• Indivisible

• Electrons revolve around nucleus

• Both a and c

The electron was discovered by thomson using cathode rays

• True yes it was discovered using cathode rays

• False it was discovered using cathode ray tubes

What base principle was used in the cathode ray experiment

• Oppositely charged particles deflect each other

• Likely charged particles attract each other

• Oppositely charged particles attract each other

• None of these
