Question
Write the partial orbital diagram for valence electrons of element Nickel
Answers
GPT-4o mini
Nickel (Ni) has an atomic number of 28, which means it has 28 electrons. The electron configuration for nickel is:
\[ \text{[Ar]} \, 3d^8 \, 4s^2 \]
To represent the valence electrons in a partial orbital diagram, we focus on the highest energy levels involved in bonding and chemical reactivity, which are typically the \( 4s \) and \( 3d \) orbitals for nickel.
### Partial Orbital Diagram
For nickel, the partial orbital diagram for its valence electrons can be represented as follows:
```
3d: ↑↓ ↑↓ ↑↓ ↑ ↑
4s: ↑↓
```
Here’s the breakdown:
- The \( 4s \) orbital has 2 electrons (shown as ↑↓).
- The \( 3d \) orbital has 8 electrons, which are arranged as pairs in the first three \( d \) orbitals and then one unpaired electron in the fourth orbital (two electrons in the first three orbitals and two in the fourth).
This representation shows the valence electron distribution for nickel, specifically highlighting how the electrons occupy their respective orbitals.
