Gold is valuable for three main reasons. 1) It is a rare metal. As with anything, the less of it that there is, the more people are willing to pay for it. 2) It has luster. Iron and aluminum, while more ostensibly useful than gold, lack unique color and luster-a must for jewelry. 3) Gold does not degrade. Unlike iron rusting, silver tarnishing, or copper oxygenating, gold from a thousand years ago is still basically in the same shape today. Its durability and lack of chemistry with most substances in our air mean that gold will last and last.

What is golds physical state at room temperature?
Gold's physical state at room temperature is solid. That's one of the reasons why gold is widely used to make various jewelry pieces.
Is rigid a property of gold?
Gold is not typically considered rigid, as it is a malleable metal. This means that gold can be easily manipulated and shaped without breaking. Its malleability is actually one of the key properties that make gold ideal for jewelry making and other applications.
When a physical change occurs in a sample of matter which is the matter that does not change?
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
What is the physical change of paper?
a physical change of paper is ex: ripping,cutting, and anything else to make the paper smaller, shorter, or less of what it was. tearing,
What property is state of matter of an object?
The property that describes the state of matter of an object is called its physical state, which can be solid, liquid, or gas. This property is determined by the arrangement and movement of the particles that make up the object.
What properties do gems have that make them valuable?

Is there a metal more valuable than gold?
Yes, there are several metals that are more valuable than gold, such as platinum, rhodium, and palladium. These metals are rarer and have unique properties that make them highly sought after for various industrial and technological applications.
What other metals have the same properties as gold?
Really none. That is why gold is so valuable. While other metals have similar properties to gold, none of them have the exact same. The closest metals to gold in terms of its properties are silver, platinum and palladium.
Which results in a more valuable product -- adding or substracting protons from gold nuclei?
Subtracting protons from gold nuclei results in a more valuable product because it can transform the gold into a different element with unique properties and applications. This process, known as transmutation, can create new materials with practical uses in various industries.
Forming a bar of gold into wire chemical or physical?
When a gold bar is shaped into a wire, the gold's chemical properties do not change. Only the physical appearance changes when gold is changed in shape. Thus, this is an example of a physical change.
Why was gold important to west africans?
Gold is valuable to West Africans because they could make gold coins and othe things.
How do gold's properties make it suitable for its uses?
Gold's properties, such as its high malleability, ductility, and corrosion resistance, make it suitable for various uses. These properties allow gold to be easily shaped into intricate designs, withstand exposure to various environments without tarnishing, and conduct electricity effectively, making it valuable in jewelry, electronics, and other industries. Additionally, its rarity and aesthetic appeal contribute to its desirability and value in society.
Can density determine the properties of gold?
Gold density is frequently a measure of purity. This is the luck of the draw because Gold is one of the most dense materials; however, a mixture of Iridium and Copper can make a yellowish metal that has the identical density to pure gold at much lower cost. It will, however, tarnish very quickly.
What physical properties of nylon and leather make them good material to use for shoelaces?
The physical properties of nylon and leather that make them good materials for shoelaces is that they are both durable and flexable
Why did Europeans want gold?
Europeans wanted to find gold because is is an valuable item and because it will make their country wealthy. :)
Is platinum is a precious stone?
Platinum is a metal. It is found in its metallic form. Its color makes it valuable as jewelry. Its chemical properties make it valuable as a catalyst.
How do gold's chemical properties make it useful?
Gold is very resistant to corrosion and is also very unreactive.
