Identify the mode of decay and state whether following equation is CORRECT or NOT. Justify. \(^{238}_{92}U\) \(\longrightarrow\) \(^{234}_{90}Th\) + \(^{4}_{2}He\) |
|
Answer» i. It involves α-decay process. ii. As uranium undergoes decay by emission of an α-particle (i.e., \(^{4}_{2}He\)), daughter nuclei (in this case thorium) ‘will observe the decrease in atomic number by 2 units and decrease in atomic mass number by 4 units. Hence, the given equation is correct. |
