Question

Write the condensed electron configuration and partial orbital diagram for Mo.

Answers

GPT-4o mini
Molybdenum (Mo) has an atomic number of 42, which means it has 42 electrons.

The condensed electron configuration for molybdenum is:

\[ \text{[Kr] 5s}^1 4d^{5} \]

This indicates that after the krypton core (which accounts for 36 electrons), molybdenum has one electron in the 5s orbital and five electrons in the 4d orbitals.

### Partial Orbital Diagram for Mo:

Here's a simplified representation of the partial orbital diagram for molybdenum:

```
4d: ↑↓ ↑↓ ↑↓ ↑ ↑
5s: ↑
```

- The "4d" subshell has five electrons, filling three orbitals completely (2 electrons each) and one additional electron in the fourth orbital.
- The "5s" subshell has one electron.

This notation reflects the distribution of electrons according to Hund's rule and the Pauli exclusion principle.
