Determine the missing product to complete the given decay scheme:
^{226}_{88}\text{Ra} \to \alpha + \,?
^{226}_{88}\text{Ra} \to \alpha + \,?
Options
- A^{230}_{90}\text{Th}
- B^{222}_{87}\text{Fr}
- C^{222}_{86}\text{Rn}
- D^{224}_{86}\text{Rn}
Correct answer
C. ^{222}_{86}\text{Rn}
Step-by-step solution
The given decay process is an alpha decay, which can be represented as:
^{226}_{88}\text{Ra} \rightarrow ^{4}_{2}\text{He} + ^{A}_{Z}\text{X}226 = 4 + AA = 22288 = 2 + ZZ = 8686\text{Rn}.
^{226}_{88}\text{Ra} \rightarrow ^{4}_{2}\text{He} + ^{A}_{Z}\text{X}226 = 4 + AA = 22288 = 2 + ZZ = 8686\text{Rn}.
