A element with atomic number 112 has recently been named as compernicim. It is named in honour odf scientist astronomer Nicolaus Copernicus. Which of the following statement about this element is not correct ?

Options

A. it belongs to d-block
B. Iht belongs to 12th group
C. Its electronic configuration in `[En] 5f ^(14) 6d^(10) 7s ^(2)`
D. It belongs to 6th period

Explanation

To solve the question regarding the element with atomic number 112, named Copernicium, we need to analyze the statements provided about this element and identify which one is incorrect. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Period and Group of Copernicium
- **Atomic Number**: 112
- **Position in Periodic Table**:
- The element with atomic number 112 is located in the 7th period of the periodic table.
- The elements in the periodic table are arranged in periods (horizontal rows) and groups (vertical columns).

### Step 2: Determine the Block of Copernicium
- **Block**:
- Elements in the periodic table are categorized into s-block, p-block, d-block, and f-block.
- Copernicium (Cn) is a d-block element because it is located in the transition metals section.

### Step 3: Electronic Configuration
- **Electronic Configuration**:
- The electronic configuration of Copernicium can be derived from that of Radon (Rn, atomic number 86).
- The configuration is:
- Radon (Rn): [Rn] 5f^14 6d^10 7s^2
- This shows that Copernicium has filled the 5f and 6d orbitals.

### Step 4: Analyze the Statements
Now, we will analyze the statements provided in the question:
1. It belongs to D-Block.
2. It belongs to 12th group.
3. It belongs to 6th period.
4. Its electronic configuration is [Rn] 5f^14 6d^10 7s^2.

### Step 5: Identify the Incorrect Statement
- **Correct Statements**:
- Statements 1, 2, and 4 are correct.
- **Incorrect Statement**:
- Statement 3 is incorrect because Copernicium belongs to the 7th period, not the 6th.

### Conclusion
The statement that is not correct about the element Copernicium (atomic number 112) is:
**It belongs to the 6th period.**

### Final Answer
The answer is option 3: "It belongs to 6th period."
