(a) Balance the nuclear equation below and hence identify Y. \(^{238}_{94}U \to ^{234}_{92}Th + Y\) (b) In a tabular form, state two of the observations in the cathode ray experiment and the corresponding deductions.
Explanation
(a) \(^{238}_{94}U \to ^{234}_{92}Th + Y\) From above balanced equation \(^4_2Y = ^4_2He\) (b) Cathode ray experiment
Observations
Deductions
The cathode rays throw a shadow at the anode.The rays will turn a light paddle wheel is the tube.
Deductions The rays are negatively charged and hence the attraction to the anode.The rays therefore have momentum and mass.
