Final answer:
Alloys made from silver and gold are malleable because they are metals with similar properties such as good electrical conductivity, the ability to be worked into thin sheets, and are solid conductors of heat and electricity.
Step-by-step explanation:
Due to similar properties, silver and gold will create alloys which are malleable. This is because both silver and gold are metals, which are characterized as being shiny, malleable, ductile, good conductors of heat and electricity, and solid at room temperature (except mercury).
Silver and gold are known to have good electrical conductivity, and when alloyed together, they retain these characteristics, including their malleability, which allows them to be hammered or pressed into thin sheets or foils without breaking. Alloys made from metals such as silver and gold maintain their conductive properties as well, making them non-brittle and non-gaseous, and they remain good conductors of electricity and heat, unlike nonmetals which are typically poor conductors.
