Is gold a soft or hard metal?
gold can be both soft and hard depending on how pure it is, pure gold (24K) is softer than a gold alloy. And the lower the number the harder it is. 10K is harder than 14K, 14K is harder than 18K, and 18K is harder than 24K (pure gold).
Is the following sentence true or false gold alloys are much harder than pure gold?
True. Pure gold is a very soft metal.
Is 18 carat gold softer than 24 carat gold?
No is actually harder 24k gold is in he's pure form 18k gold have a % of alloys to make it harder.
Is silver harder than 9 carat gold?
9 carat gold is only 33% Gold and 66% copper. Pure Silver is soft... To answer the question - the 9 carat Gold is harder than the Silver.
Why is 9 carat gold harder than pure gold?
9 carat gold is harder because it is mixed with other types of metal which are harder than gold. Gold is a fairly soft metal. Historically cold coins were sometimes bitten to check how soft or pure the gold was . Another historical practice was to scrape or peel off the edge of the gold coin ( keeping it looking circular of course!) and collect these scraps for melting. This is the reason why nowadays coins are edged with serrated markings, called reedings..to prevent you from taking a little bit off the edge!

Difference between 10k and 14k gold?
24K gold is pure gold. Pure gold is very soft, and can bend or scratch easily. So they mix it with other metals to make it harder and more durable. Higher amounts of other metals lowers the karate value. So 14K gold has more gold than 10K gold. 14K gold is also softer than 10K gold, but harder than pure gold.

Is 18 karat gold better than 9 karat?
24K is pure gold. Any number smaller than that means less gold and more alloy metals. Alloy metals are mixed with gold to make it harder. Pure gold would be so soft that it would deform or get scratches and nicks in it.
Is aluminum harder than lead or copper?
It depends on the alloy and temper of each material. Beryllium copper alloys are harder than the softest aluminum alloys, and high-strength aluminum alloys are harder than pure copper (which is quite soft). And almost every metal is harder than lead, except a few such as gold.
GOld in a ring is an element?
Yes, the gold in jewelry (such as rings) is an element. But jewelry is not made of pure gold, because pure gold is too soft. The other metals make it harder, and can affect the color of the jewelry (this is how you get 'white gold' - different metals make it look more white than other gold jewelry).
10 k gold to pure gold?
10K gold is 10 parts gold to 14 parts of ... some other metal (usually mostly silver with some copper,nickel, and/or zinc). The reason for using gold alloys rather than pure gold in jewelry is that a) other metals are cheaper than gold and b) the alloy is considerably harder than pure gold, so it stands up better to wear and tear. It is possible to refine 10K gold to pure gold, if that's what you're asking, but the easiest way involves strong acids, so you may just want to sell it as is to a professional refiner.
How do you test 14k gold jewelry for authenticity?
See if your finger can scratch the gold. If your finger nail can than you have pure gold. But because gold is weak like that the jewelry stores usually put other minerals to make it harder.
