**Question:**
The nuclear reaction shown below is an example of what type of process?

\[ \text{}^{224}_{90}\text{Th} \rightarrow \text{}^{220}_{88}\text{Rn} + \text{}^{4}_{2}\text{He} \]

**Options:**
- ○ translation
- ○ fission
- ○ beta emission
- ○ fusion
- ○ alpha emission

**Explanation:**
This question is about identifying the type of nuclear reaction occurring. The equation shows Thorium-224 (Th) decaying into Radon-220 (Rn) while emitting a Helium-4 nucleus (\( \text{}^{4}_{2}\text{He} \)), which is characteristic of an alpha emission. 

Alpha emission involves the release of an alpha particle (two protons and two neutrons) from a radioactive nucleus, reducing the atomic number by 2 and the mass number by 4.
