The element whose electronic configuration is `1s^(2), 2s^(2)2p^(6), 3s^(2)` is a`//`an

Options

A. Metal
B. Metalloid
C. Inert gas
D. Non-metal

Explanation

To determine the classification of the element with the electronic configuration \(1s^2, 2s^2, 2p^6, 3s^2\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Electronic Configuration**:
The given electronic configuration is \(1s^2, 2s^2, 2p^6, 3s^2\).

2. **Calculate the Atomic Number**:
To find the atomic number, we need to add the total number of electrons:
\[ 2 \, (from \, 1s^2) + 2 \, (from \, 2s^2) + 6 \, (from \, 2p^6) + 2 \, (from \, 3s^2) = 12 \]
Therefore, the atomic number is \(12\).

3. **Determine the Element**:
Using the atomic number, we can identify the element. The element with atomic number \(12\) is Magnesium (Mg).

4. **Classify the Element**:
Magnesium is located in Group 2 of the periodic table, which is known as the alkaline earth metals. Elements in this group are metals.

5. **Conclusion**:
Therefore, the element with the electronic configuration \(1s^2, 2s^2, 2p^6, 3s^2\) is a metal.

### Final Answer:
The element is a **metal**.
