Gold is a chemical element with the symbol Au and atomic number 79. It is a dense, soft, malleable and ductile metal with a bright yellow color and luster, the properties of which remain without tarnishing when exposed to air or water
It is very important for indians as they use it in every occation like weddings,functions,festivals etc.there is a history of its popularity.it has unique chemical properties which makes it valuable and the superior of all metals.
What else can I help you with?
Which is softer gold or iron?
Gold is softer than iron. Gold is a highly malleable metal, meaning it can be easily shaped and molded, while iron is much harder and more rigid. This is why gold is often used in jewelry and decorative items, while iron is used for more industrial purposes.
Which is odd one out in glass alminum iron gold?
The odd one out is aluminum. While gold and iron are both metals that are commonly found in their elemental forms and have significant uses in various applications, aluminum is a lightweight metal that is primarily used in alloys and is more reactive than the other three. Additionally, gold is a precious metal, while aluminum and iron are more widely used in industrial applications.
Is silver more reactive than gold?
Yes, silver is more reactive than gold. Silver is more chemically reactive because it has a tendency to form compounds with other elements more readily than gold. Gold is known for its resistance to corrosion and is considered a noble metal.
Why can iron be used to get copper from copper sulfate?
Iron is more reactive than copper, so when iron is added to copper sulfate solution, iron displaces copper in the reaction and forms iron sulfate. This process is known as a displacement reaction. This allows copper to be extracted from copper sulfate solution using iron.
Is silver stronger than iron?
No, in terms of strength, iron is generally stronger than silver. Iron has a higher tensile strength and is more commonly used in structural applications where strength is required. Silver is valued for its beauty and conductivity rather than its strength.
How is ore used in a sentence?
Fortunately, iron ore is much more common than gold ore; gold may be pretty but iron is used to make steel.
Which is softer gold or iron?
Gold is softer than iron. Gold is a highly malleable metal, meaning it can be easily shaped and molded, while iron is much harder and more rigid. This is why gold is often used in jewelry and decorative items, while iron is used for more industrial purposes.
Why is gold used more then iron in jewelry?
No
Which physical property did prospectors use to tell the difference between iron pyrite and gold?
Prospectors used the physical property of density to differentiate between iron pyrite and gold. Gold is denser than iron pyrite, so prospectors could use the weight of a sample to determine whether it was more likely to be gold or iron pyrite.
Why is gold not used for sacrificial protection?
Sacrificial protection is only effective if the metal used for sacrificial protection is more reactive than Iron in the reactivity series. Since gold is one of the least reactive metals in the reactivity series, it would not get oxidized in the place of Iron. A more reactive metal than Iron, e.g. Zinc, is used as the Zinc metal would oxidize in the place of iron, thus preventing Iron from rusting.
Why is gold better used than iron and magnesium for jewelry?
Gold is preferred for jewelry over iron and magnesium because it does not tarnish, corrode, or rust. Gold is also more malleable and can be easily shaped into intricate designs, making it a popular choice for fine jewelry. Additionally, gold's rarity and luster give it a sense of luxury and value that iron and magnesium do not possess.
Why can panning be used to obtain the element gold but cannot be used to obtain the element iron?
One reason is that gold is considerably denser than iron and therefore sinks more consistently to the bottom of a shaken pan. Another reason is that iron rarely occurs in nature in elemental form, while gold relatively often does occur naturally in elemental form.
Why can iron be used used to get copper from copper sulfate solution?
Iron is more reactive than copper
Which metal is more commonly used in electrical wiring, copper or iron?
Copper is more commonly used in electrical wiring than iron.
Which metal is more commonly used in electrical wiring, iron or copper?
Copper is more commonly used in electrical wiring than iron.
Why are gold alloys more commonly used for jewelry than pure gold?
Pure gold is too soft to be used in jewelry.
Why did iron become more widely used than bronze?
Iron became more widely used than bronze because it was more readily available and easier to extract from ores. Iron also had other advantages over bronze, such as being harder and more durable, making it better for tool and weapon production. Additionally, iron was cheaper and more abundant than bronze, making it accessible to a larger number of people.
