Question

How did Thomson conclude that cathode rays consist of negatively charged particles and term them as 'electrons'?
​

Answer 1

Answer:

jj Thomson conclude electron on his discharge tube experiment when he saw some charged particles moving towards anode . since anode is positive and electron was getting attracted toward anode he concluded that cathode consist negative charge becoz it was repelling electrons

Answer 2

In Thomson's model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electrons' negative charges, like negatively charged “plums” surrounded by positively charged “pudding”.
