Ti, Element #22 Titanium is highly resistant to chemical attack and has the highest strength to weight ratio of any metal. This is a sample of .999 commercially pure, grade 2 titanium in the form of a square periodic table entry. One side shows the simple entry, as seen on classroom walls, showing the atomic number (22), the atomic weight (47.87), the symbol (Ti), and the name (titanium). On the other side is a more complete entry providing additional technical information including the melting point, density, purity, electron configuration and sample weight of the sample. On the right hand side is the circular Bohr model of the atom. Solid titanium 9 grams 1 inch or 2.5 cm width If we take an example weight of 9 grams, convert that to moles, and multiply by Avogadro’s number, you’re getting an astounding 11.3222 × 1022, or 11 octilion titanium atoms! Now that’s value! © Shire Post Mint. All rights reserved. **SAMPLE COIN HAS HOLE**
