Answer
Answer:
(7) i. Energy is released ii. New nuclei or particles are formed (8)
| Type of disintegration | Example |
|---|---|
| Alpha - decay | ({92}^{238}U\rightarrow{90}^{234}Th + _{2}^{4}He) |
| Beta - decay | ({6}^{14}C\rightarrow{7}^{14}N+_{ - 1}^{0}e) |
| (9) | |
| i. The speed of light in a vacuum ((3.00\times 10^{8}m/s)) | |
| ii. The mass defect (the difference in mass between the original nucleus and the sum of the masses of its decay products) | |
| iii. (c = 3.00\times 10^{8}m/s), (c^{2}=(3.00\times 10^{8}m/s)^{2}=9.00\times 10^{16}m^{2}/s^{2}) |
