The IUPAC symbol for the element with atomic number 119 would be:

Options

A. uue
B. une
C. uun
D. unh.

Answer

To determine the IUPAC symbol for the element with atomic number 119, we can follow these steps:

### Step 1: Identify the Prefixes for Naming
The IUPAC naming convention uses specific prefixes for numbers:
- 0: nil
- 1: un
- 2: bi
- 3: tri
- 4: tetra
- 5: penta
- 6: hexa
- 7: hepta
- 8: octa
- 9: nona

### Step 2: Break Down the Atomic Number
The atomic number 119 can be broken down into its components:
- The first digit is 1, which corresponds to the prefix "un".
- The second digit is 1 again, which again corresponds to the prefix "un".
- The last digit is 9, which corresponds to the prefix "nona".

### Step 3: Combine the Prefixes with the Suffix
According to the IUPAC naming convention, we combine these prefixes with the suffix "ium":
- For 1: "un"
- For 1: "un"
- For 9: "nona"

Thus, we combine them to form the name:
- un + un + nona + ium = "ununennium"

### Step 4: Formulate the IUPAC Symbol
To create the IUPAC symbol, we take the first letter of each part of the name:
- From "un" (1st un): U
- From "un" (2nd un): U
- From "nona" (9): E

Therefore, the IUPAC symbol for the element with atomic number 119 is:
- UUE

### Final Answer
The IUPAC symbol for the element with atomic number 119 is **UUE**.
