Question:
If titanium has a valence of +4 like carbon, what would happen if you crystallized titanium atoms into a tetrahedral form like diamond?



Replies:
Because two elements have the same oxidation number (valence) does not mean that they form the same kinds of chemical bonds. Titanium vs. Carbon is a good example. Titanium (in its elemental form) bonds with other titanium atoms forming metallic bonds. In contrast carbon, in its various elemental forms (diamond, graphite, C60, C72, etc.) forms covalent bonds. The difference in bonding types results in different properties. What might happen with titanium at very high temperatures and pressures is a different issue. Under extreme conditions some strange things happen.
