What is the electron configuration for Titanium?

The electron configuration for Titanium is [Ar] 4s² 3d². This configuration reflects Titanium's atomic number, which is 22, meaning it has 22 electrons.

In the context of electron configuration, the Aufbau principle states that electrons fill orbitals starting from the lowest energy levels to the highest. The 4s orbital is filled before the 3d orbital because it has a lower energy level than the 3d orbital for the first few elements, including Titanium. After filling the 4s orbital with 2 electrons, the remaining electrons (22 total minus 2 for 4s) go into the 3d orbital. For Titanium, this accounts for 2 additional electrons in the 3d orbital, resulting in a complete electron configuration of [Ar] 4s² 3d².

This understanding of orbital filling helps ensure accurate representations of electron distributions for elements in the periodic table.
