Why are metals sometimes added to gold?

to make it softer and more malleable

to improve the value of gold

to raise its melting point

to make gold stronger and more durable

to change its color

are you sure

Sorry, I made a mistake in my response. One of the main reasons metals are added to gold is actually to make it stronger and more durable. This is known as alloying gold. The addition of metals like copper, silver, zinc, or nickel can change the properties of gold to better suit specific applications, such as jewelry making or industrial uses.
