Answer 2

Dear Student,

● JJ Thomson's atomic model -

• aka plum pudding model of atom
• Thomson stated that the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.

● Thomson's Cathode ray experiment -

• Thomson bombarded atoms with cathode rays to know structure of atom.
• The particles in the gas were attracted to positive plate.
• Thus they must be negatively charged. Thomson named them electrons.
• From this he concluded that cathode rays were made up of negative charged particles.

Hope this helps you..
