* Titanium's Electron Configuration: Titanium (Ti) has an atomic number of 22. This means it has 22 electrons. Its electron configuration is: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d².
* Valence Electrons: Valence electrons are the ones in the outermost shell, which are involved in bonding. Titanium's valence electrons are in the 4s and 3d orbitals. This means it has four valence electrons.
* Lewis Dot Diagram: In a Lewis dot diagram, we represent the valence electrons as dots around the element's symbol. Titanium would have four dots, not three, representing its four valence electrons.
Important Note: While titanium has four valence electrons, it often loses all four to become a +4 cation. This is because of the tendency of transition metals to lose electrons from both their s and d orbitals.
