Uub is the symbol for the element with atomic number-

Options

A. Option 1. 102
B. Option 2. 108
C. Option 3. 110
D. Option 4. 112

Answer

To determine the element represented by the symbol "Uub" with its atomic number, we can follow these steps:

### Step 1: Understand the Symbol
The symbol "Uub" is composed of two parts: "U" and "b". According to IUPAC nomenclature for elements with atomic numbers greater than 100, we can break down the symbol as follows:
- "U" stands for "un" which corresponds to the atomic number 1.
- "b" stands for "bi" which corresponds to the atomic number 2.

### Step 2: Combine the Atomic Numbers
When we combine these parts:
- The first "U" (un) corresponds to 1.
- The second "U" (un) corresponds to another 1.
- The "b" (bi) corresponds to 2.

Thus, the atomic number represented by "Uub" is calculated as:
1 (from the first U) + 1 (from the second U) + 2 (from b) = 1 + 1 + 2 = 4.

### Step 3: Identify the Element
The element with atomic number 4 is Beryllium (Be).

### Conclusion
Therefore, the symbol "Uub" corresponds to the element Beryllium with atomic number 4.
