Why vessels made of metals lose their shine after few days?
Oxidation of the metal
Why do metals often lose their shine and appear dull?
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
Why vessels made of metals lose their luster?
Vessels made of metals lose their luster primarily due to oxidation and tarnishing. When exposed to air and moisture, metals react with oxygen and other environmental elements, forming oxides or sulfides that dull their surface. Additionally, exposure to pollutants and chemicals can accelerate this process. Regular cleaning and polishing can help maintain their shine and protect against these effects.
When metals react with other elements do the atoms of the metals gain or lose?
Metals are likely to make anions. So they lose electrons to get a positive charge. The other elements gain electrons and get negatively charged.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
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.

Why is gold used jewelry?
because it does not lose its shine, because it is a very slow reactor to air, meaning it doesn't break down or rust like other metals. also because it is rare, so it means it is special and very expensive so you look expensive!
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.
Does gold have the tendency to lose or gain electrons in a chemical reaction?
Gold has a tendency to lose electrons in a chemical reaction, which is why it is known as a "noble metal." This property makes gold less reactive than other metals and contributes to its resistance to corrosion.
Why you preferr gold as metal in jewelry?
sliver tarnishes much worse than gold and requires a lot of upkeep and can lose its shine

How do I prove to my customers that my jewelry are real when I sell them at an antique farmers market?
Use a piece of unglazed ceramic material. Rub the gold against it. Fool's gold will leave a black streak, and real gold will leave a golden streak. This ofcourse works for gold and you will lose a bit of gold in the process. There are other methods for other metals and stones.
What is the different between reactive and non reactive metals?
one reacts and one doesn't
What block of elements on the periodic table will oxidize or lose elements?
They lose electrons, not elements. These are metals. Group I metals (IA or alkali metals), Group 2 metals (IIA or alkaline earth metals), transition metals (groups 3 thru 12), and all other metals.
