Which of the following is the correct IUPAC name of an element having atomic number 102?

Options

A. ununnilium
B. ununnilium
C. unnilennium
D. none of these

Answer

To determine the correct IUPAC name of the element with atomic number 102, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number**: The atomic number given is 102. This number is crucial for determining the IUPAC name.

2. **Break Down the Atomic Number**: The atomic number 102 can be broken down into its digits: 1 and 0 and 2.

3. **Assign Prefixes Based on Digits**:
- For the digit **1**, the prefix is **un**.
- For the digit **0**, the prefix is **nil**.
- For the digit **2**, the prefix is **bi**.

4. **Combine the Prefixes**: Now, we combine these prefixes in the order of the digits:
- Start with **un** (for 1),
- Then **nil** (for 0),
- Finally **bi** (for 2).

5. **Add the Suffix**: After combining the prefixes, we add the suffix **-ium** to indicate that it is a chemical element. Therefore, we have:
- **un-nil-bi** + **-ium** = **unnilbium**.

6. **Final IUPAC Name**: The final IUPAC name for the element with atomic number 102 is **unnilbium**.

### Conclusion:
The correct IUPAC name for the element with atomic number 102 is **unnilbium**.
