White gold and is known as the (platinum), and platinum chemical element symbol pt in the periodic table, and ranks among the elements that transition metal, and
its physical properties hardness, magnetic appeasement, and the tensile strength of the 125-245 element Gigabascal, the coefficient of volume has 230 Gigabascal, and a boiling point of 3825 c, The melting temperature 17680c. The origin of platinum (Plata), a Spanish word that means (small silver), a precious metal, and color of white, gray, and features a platinum largest iron metal strongly but its flexibility, such as gold.
The advantage of this metal strength and not rust, and has to maintain its luster when exposed to air capacity, due to the fact that platinum does not react with oxygen, is not affected by acids that dissolve other metals. Platinum and melted using a mixture of nitric acid and hydrochloric acid, and combine with arsenic and silicon, and is characterized by white gold rising value compared with
