Answers
GPT-4o mini
Molybdenum (Mo) has an atomic number of 42. The condensed electron configuration for molybdenum is:
**\[ \text{[Kr]} \, 5s^2 \, 4d^4 \]**
This means that after filling the electron configuration of krypton (\[ \text{Kr} \]), the next electrons fill the 5s orbital before starting to fill the 4d orbitals.
### Partial Orbital Diagram for Mo
Here's a simplified depiction of the energy levels and orbitals for Mo:
```
Energy Level (n=5) : ↑↓ 5s (2 electrons)
Energy Level (n=4) : ↑↓ 4d (4 electrons)
↑ ↑ ↑ ↑
```
This diagram indicates:
- The **5s** subshell holds 2 electrons (paired).
- The **4d** subshell has 4 electrons (which can be represented as one in each of the four available orbitals with one unpaired electron in the last orbital).
### Note
In the 4d subshell, according to Hund's Rule, each of the four 4d orbitals is half-filled before any orbital gets a second electron, hence the representation.
**\[ \text{[Kr]} \, 5s^2 \, 4d^4 \]**
This means that after filling the electron configuration of krypton (\[ \text{Kr} \]), the next electrons fill the 5s orbital before starting to fill the 4d orbitals.
