C. Uno
D. Une

Answer

To find the symbol of the element with atomic number Z = 109, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number**: The atomic number given is Z = 109. This indicates the position of the element in the periodic table.

2. **Understand IUPAC Naming**: For elements with atomic numbers greater than 100, the International Union of Pure and Applied Chemistry (IUPAC) has a systematic way of naming them based on their atomic numbers.

3. **Break Down the Atomic Number**:
- The atomic number 109 can be broken down into its digits:
- 1 → "un"
- 0 → "nil"
- 9 → "enn"

4. **Combine the Parts**:
- Combine the parts derived from the digits:
- From 1: "un"
- From 0: "nil"
- From 9: "enn"
- This gives us "unnilenn".

5. **Add the Suffix**: According to IUPAC naming conventions, we add the suffix "-ium" to the combined name:
- Therefore, "unnilenn" + "ium" = "unnilennium".

6. **Final Symbol**: The symbol for the element with atomic number 109 is therefore **Uue** (the symbol for unnilennum).

### Final Answer:
The symbol of the element with atomic number Z = 109 is **Uue**.
