Question

**Electron Configuration Evaluation**

Decide whether the electron arrangement shown below represents a ground state, excited state, or impossible electron arrangement.

[2 attempts only. 50% penalty]

Configuration:
- [Ar]
- 4s: ↑
- 3d: ↑ ↑
- 4p: ↓

**Options:**

- Impossible
- Excited state
- Ground state

*Check*

**Explanation of the Diagram:**

The diagram starts with the noble gas core notation [Ar], followed by:

- **4s Orbital:** Contains one upward arrow (↑) indicating one electron.
- **3d Orbitals:** Two upward arrows (↑ ↑) indicating two unpaired electrons.
- **4p Orbital:** One downward arrow (↓) indicating one electron.

This setup is used to analyze the electron arrangement in terms of electron configuration rules.

Expert Solution

Step 1

Impossible

the given electronic configuration is an impossible configuration because it is not following any of the following rule .
1) Aufbau principle - It states that first electrons are filled in atomic orbitals of lower energy after that atoms will be filled in highest energy level .
3) Hunds rule - according to this rule every orbital of subshell singly occupied with one electron after that only pairing occurs in orbital .
