Which of the electroic configuration is of a noble gas atom in the following ?

Options

A. `1s^(2),2s^(2),2p^(6),3s^(2),3p^(3)`
B. `1s^(2),2s^(2),2p^(6),3s^(2),3p^(1)`
C. `1s^(2),2s^(2),2p^(6),3s^(2),3p^(6)`
D. `1s^(2),2s^(2),2p^(6),3s^(2),3p^(4)`

Explanation

To determine which electronic configuration corresponds to a noble gas atom, we need to understand the characteristics of noble gases and their electronic configurations.

### Step-by-Step Solution:

1. **Identify Noble Gases**: Noble gases are elements found in Group 18 of the periodic table. They are characterized by having a complete outer electron shell, which makes them very stable and largely unreactive. The noble gases include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn).

2. **Understanding Electronic Configuration**: The electronic configuration of an atom describes the distribution of electrons in its atomic orbitals. For noble gases, the outermost shell (valence shell) is completely filled. This means that for noble gases in the p-block, the p-orbital can hold a maximum of 6 electrons.
