Tungsten shines for the same reason that any other metal shines; the metallic bond creates an electron cloud which readily reflects light.


Why do vessels made of metals lose shine after few days?

Most metals lose their shine as they react with gases in the atmosphere or in a liquid.. The surface layer may react to fom an oxide, hydrated oxides, sulfide, sulfates, carbonates. Generally ths process makes the surface dull and it may get pitted. The process is called corrosion when it is iron rusting and tarnishing when it is silver forming black silver sulfide or copper forming a mixture of greenish products, "patina" whose composition depends on the location.Some metals do not lose their shine. Common examples are gold and platinum which are used as jewellery. Aluminium still looks shiny but there is thin layer of aluminium oxide which prevents the reactive aluminium metal from corroding.

What is the appearance of gold?

Gold is a bright, yellow metal with a lustrous shine. It is dense, malleable, and ductile, making it ideal for jewelry and currency. Over time, gold can develop a patina or tarnish, but it can be easily polished to restore its original shine.


Does gold tarnish?

Gold does not tarnish. It is a highly stable and non-reactive metal, which means it does not rust or corrode like some other metals when exposed to air or moisture. This is one reason why gold is valued for its durability and long-lasting shine.
