The element with atomic number 113 has recently been discovered . Its electronic configuration is similar of that of

Options

A. Si
B. Ga
C. Bi
D. At

Explanation

To determine the electronic configuration of the element with atomic number 113 and identify which element it is similar to, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Element**: The element with atomic number 113 is known as Nihonium (Nh).

2. **Locate the Element in the Periodic Table**: Nihonium is located in Group 13 of the periodic table. Group 13 elements are known as the boron group.

3. **Understand Electronic Configuration**: The electronic configuration of an element describes the distribution of electrons in its atomic orbitals. For elements in the same group, the outermost electron configuration (valence electrons) is similar.

4. **Determine the Electronic Configuration of Nihonium**:
- The electronic configuration of Nihonium (Nh) can be derived from the previous elements. It is:
\[ [Rn] 5f^{14} 6d^{10} 7s^{2} 7p^{1} \]
- Here, [Rn] represents the electron configuration of Radon, which is the nearest noble gas preceding Nihonium.

5. **Identify Similar Elements**:
- Elements in Group 13 include Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), Thallium (Tl), and Nihonium (Nh).
- The electronic configuration of Gallium (Ga), which is in the same group, is:
\[ [Ar] 3d^{10} 4s^{2} 4p^{1} \]
- While the principal quantum numbers differ, the valence shell configuration (the outermost electrons) is similar, as both have one electron in the p-orbital.

6. **Conclusion**: The electronic configuration of Nihonium (Nh) is similar to that of Gallium (Ga) in terms of the outermost electrons, as both belong to Group 13.

### Final Answer:
The element with atomic number 113 (Nihonium) has an electronic configuration similar to that of Gallium (Ga).
