A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride.

Hope you understand from it
also the values are different.
The question for the below attachment is
Q) Gold is 19 times as heavy as water and copper is 9 times as heavy as water. The ratio, in which the two metals should be mixed, so that the mixture is 15 times as heavy as water, is
And the answer for it was, 6:4 = 3:2
For this it is
20-17=3 and 17-13=4
So, the answer is 4:3.
