Hafnium (Hf) has an atomic number of 72. To write its condensed electron configuration, we can follow the order of filling the orbitals according to the Aufbau principle.

The condensed electron configuration of hafnium is:

\[ \text{[Xe]} 4f^{14} 5d^{2} 6s^{2} \]

This indicates that hafnium has the same electron configuration as xenon (the nearest noble gas) plus the additional electrons that fill the 4f, 5d, and 6s orbitals.

For the partial orbital diagram, we can represent it as follows:

```
6s: ↑↓
5d: ↑↓ ↑
4f: ↑↓ ↑↓ ↑↓ ↑↓ ↑↓
```

In this diagram:
- The 6s orbital has 2 electrons (paired).
- The 5d orbital has 2 electrons (one pair and one unpaired).
- The 4f orbital is fully filled with 14 electrons (7 pairs).

This illustration helps visualize the distribution of electrons in the orbitals of hafnium.
