Options

A. Ra and Ca
B. Cf and Ca
C. Cf and Cu
D. Ra and He

Answer

To answer the question regarding the synthetic production of Oganesson, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Elements Involved**: Oganesson (Og) is a synthetic element with atomic number 118. It is produced through nuclear reactions involving heavy elements. The key elements involved in its synthesis are Californium (Cf) and Calcium (Ca).

2. **Determine the Isotopes**: The isotopes used in the reaction are Californium-249 (Cf-249) and Calcium-48 (Ca-48). These isotopes are chosen due to their suitable mass and nuclear properties for fusion.

3. **Understand the Collision Process**: The synthesis of Oganesson occurs when Californium-249 collides with Calcium-48. This collision leads to a nuclear reaction where the two nuclei fuse together.

4. **Write the Reaction Equation**: The nuclear reaction can be represented as:
\[ \text{Cf-249} + \text{Ca-48} \rightarrow \text{Og-294} + 3 \text{n} \]
Here, Og-294 is the resulting isotope of Oganesson, and 3 neutrons (n) are released during the reaction.

5. **Calculate the Mass Numbers**:
- Californium-249 has a mass number of 249.
- Calcium-48 has a mass number of 48.
- The total mass number before the reaction is \( 249 + 48 = 297 \).
- After the formation of Oganesson-294 and the release of 3 neutrons (mass number = 1 each), the total mass number after the reaction is \( 294 + 3 = 297 \), which is balanced.

6. **Conclusion**: The synthetic production of Oganesson occurs through the collision of Californium-249 and Calcium-48, resulting in the formation of Oganesson-294 and the release of neutrons.

### Final Answer:
Oganesson has been synthetically produced by the collision of Californium and Calcium.
