The IUPAC name of element having atomic number 108 is

Options

A. Unniloctium
B. Ununoctium
C. Nilniloctinium
D. Ununoctinium

Answer

To determine the IUPAC name of the element with atomic number 108, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number**: The atomic number given is 108.

2. **Break Down the Atomic Number**: We will break down the atomic number into its individual digits. The atomic number 108 consists of the digits 1, 0, and 8.

3. **Assign IUPAC Notations**:
- For the digit **1**, the IUPAC notation is **un** (from "unus").
- For the digit **0**, the IUPAC notation is **nil** (from "nullus").
- For the digit **8**, the IUPAC notation is **oct** (from "octo").

4. **Combine the Notations**: Now, we will combine the notations we have:
- 1 → un
- 0 → nil
- 8 → oct
- Therefore, combining these gives us: **un + nil + oct**.

5. **Add the Suffix**: According to IUPAC naming conventions, we add the suffix **-ium** to the combined notation. Thus, we get:
- **un + nil + oct + ium = unniloctium**.

6. **Final IUPAC Name**: The IUPAC name for the element with atomic number 108 is **unniloctium**.

### Summary:
- The IUPAC name of the element with atomic number 108 is **unniloctium**.
