Write the IUPAC Symbol for the element having atomic number 120.

Answer

To determine the IUPAC symbol for the element with atomic number 120, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Atomic Number**: The atomic number given is 120.

2. **Break Down the Atomic Number**: The atomic number 120 can be broken down into its numeral components:
- 1 = "un"
- 2 = "bi"
- 0 = "nil"

3. **Combine the Prefixes**: Combine the prefixes derived from the digits:
- From "1" we get "un"
- From "2" we get "bi"
- From "0" we get "nil"
- Therefore, combining these gives us "unbi" + "nil".

4. **Add the Suffix**: The IUPAC naming convention for elements includes a suffix. For elements, we typically use "ium" as the suffix. Thus, we add "ium" to the combined prefixes:
- This results in "unbinilium".

5. **Write the Symbol**: The IUPAC symbol for the element is formed by taking the first letter of the name and the first letter of the second part of the name:
- The symbol is "Ubn", where "U" is capitalized and "bn" is in lowercase.

### Final Answer:
The IUPAC symbol for the element with atomic number 120 is **Ubn**.
