(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.
(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. |
