its not stable because last orbit need to loose electron to be stable
Platinum is highly stable. It is among the most inert elements.
Tantalum, platinum and gold are very stable metals and have low reactivity.
They do not combine with or interact with most other elements or compounds. ... radioactive. No radioactive isotope of platinum has any commercial application.
Platinum typically forms a Pt2+ ion. This means that platinum has lost two electrons to achieve a more stable electron configuration.
The noble gasses, gold and platinum.
A very low chemical reactivity as for noble gases or platinum metals.
Iridium has an atomic mass of 192 (192.217)
The way to apply for any credit card including a platinum credit card would be to go to the website and apply. You need a stable job and good credit too.
Platinum does not seem to have discovered allotropes; instead it has isotopes which are the nearest thing from what I could discover online. Not only that but platinum is so rare no one really has enough money to test it enough to discover whether it does have allotropes are not.
Platinum is less reactive, by reacting with aqua regia only in the hot while gold not. Platinum potassium cyanide is not known while Gold potassium cyanide is obtained quite simply. In contrast, Platinum is somewhat lower on the electromotive scale - 1.2v against 1.5-1.6v for gold
Noble metals such as gold, platinum, and silver are among the most stable metals due to their resistance to corrosion and chemical reactivity. These metals have a high level of stability in various environments and are often used in applications requiring durability and longevity.
Platinum is the least reactive among the noble metals due to its high resistance to corrosion and chemical attack. This is because platinum possesses a stable electron configuration, which makes it less likely to form chemical bonds with other elements. Additionally, platinum has a strong metal-metal bond within its structure, further contributing to its inertness.
