**Electron Configuration Question**

**Question 6**

The following electron configuration should represent a ground state atom of carbon. What is the error in this configuration?

**Configuration Diagram:**

- **1s orbital box**: Contains two electrons, represented by arrows pointing in opposite directions (indicating paired electrons with opposite spins).
- **2s orbital box**: Contains two electrons, also paired with opposite spins.
- **2p orbital boxes**: The first box has two electrons paired with opposite spins, while the second and third boxes are empty.

**Options for Error Identification:**

1. It violates Hund's rule because it pairs electrons in the 2px orbital of the 2p subshell before placing one electron in the 2py and 2pz orbitals.
2. It violates Hund's rule because it does not show unpaired valence electrons with the same spin.
3. It violates Aufbau's order of filling by placing electrons in the 2p subshell before the 2s subshell is full.
4. It violates Pauli exclusion principle by placing two electrons with the same spin magnetic quantum number in an orbital.
5. There is no violation.

**Feedback provided:**

All paired electrons have opposite spin. There is something off with the paired electrons in the 2px orbital, though.
