According to IUPAC nomenclature the name of elements having atomic numbers 101 and 116 are

Options

A. unilibium and unnilhexium
B. unnillunium and ununhhexium
C. unnliquadium and unnibium
D. none of the above

Answer

To determine the IUPAC names of the elements with atomic numbers 101 and 116, we will follow the systematic naming rules established by IUPAC. Here’s a step-by-step solution:

### Step 1: Identify the atomic numbers
- We need to find the names for elements with atomic numbers 101 and 116.

### Step 2: Name the element with atomic number 101
- According to IUPAC nomenclature:
- The prefix for 1 is "un".
- The prefix for 0 is "null".
- The prefix for 1 again is "un".
- Finally, we add the suffix "ium".

Combining these, the name for element 101 is:
- **Unnilunium (Unu)**

### Step 3: Name the element with atomic number 116
- For atomic number 116, we follow the same naming convention:
- The prefix for 1 is "un".
- The prefix for 1 again is "un".
- The prefix for 6 is "hex".
- Finally, we add the suffix "ium".

Combining these, the name for element 116 is:
- **Ununhexium (Uuh)**

### Final Answer
- The names of the elements with atomic numbers 101 and 116 are:
- 101: Unnilunium (Unu)
- 116: Ununhexium (Uuh)
