Nickel (Ni) has an atomic number of 28. Here’s how to represent its electron configuration in various formats:
Full Electron Configuration
The full electron configuration of Nickel is: \[ 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8 \]
Condensed Electron Configuration
Using the nearest noble gas (Argon, Ar) as a reference, the condensed electron configuration is: \[ [Ar] 4s^2 3d^8 \]
Partial Orbital Diagram
The partial orbital diagram for Nickel would look like this:
1s: ↑↓
2s: ↑↓
2p: ↑↓ ↑↓ ↑↓
3s: ↑↓
3p: ↑↓ ↑↓ ↑↓
4s: ↑↓
3d: ↑↓ ↑↓ ↑↓ ↑
(Note: In the 3d subshell, one of the orbitals has only one electron initially placed to fill before pairing occurs, following Hund’s rule.)
Inner Electrons
The inner electrons for Nickel include all electrons in the filled shells before the outermost shell. For Nickel, the inner electrons consist of: \[ 1s^2, 2s^2, 2p^6, 3s^2, 3p^6 \] This totals to 20 inner electrons.
Summary
- Full Electron Configuration: \( 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^8 \)
- Condensed Electron Configuration: \( [Ar] 4s^2 3d^8 \)
- Inner Electrons: 20
