What is the properties and uses of platinum?
Platinum is a silver-white metal — it was once known as “white gold.” It is extremely resistant to tarnishing and corrosion (which makes it known as a “noble metal”) and is very soft and malleable, making it easy to shape; ductile, making it easy to stretch into wire; and unreactive, which means it doesn’t oxidize and …
What are Platinums properties?
Platinum is a lustrous silvery-white, malleable, ductile metal and a member of group 10 of the periodic table of the elements. It has the third highest density, behind osmium and iridium.
What are the properties and uses of beryllium?
Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.
What are the anomalous properties of beryllium?
Beryllium: The anomalous properties of beryllium is mainly due to its small size, high electronegativity, high ionization energy and high polarizing power compared to the other elements in the block.
What are 5 uses for platinum?
Platinum uses come from 5 major sectors:
- Platinum Automotive Catalytic Converter Exhaust Pollution Prevention (heavy in diesel)
- Platinum Jewelry.
- Platinum Petrochemical Uses.
- Platinum Investment Demand (platinum bullion bars, coins, ETFs)
- Platinum Industrial Applications.
What is the property of silicon?

Why beryllium has high melting and boiling point?
The stronger the metallic bond, the more energy is required to take atoms apart and, therefore, the higher MP and BP. Beryllium is the lightest of all the alkaline earth metals. It has higher melting and boiling points compared to other elements in group 2.
