• A. $Cu$ and $Au$
• B. $Li$ and $Na$
• C. $Fe$ and $Hg$
• D. All of the above

Answer 1

The correct option is A $Cu$ and $Au$

Metals combined with other substances to make them stronger, harder, lighter, or better in some other way. An alloy like this will form only if the atoms of the base metal and those of the alloying agent are of roughly similar size. In most substitution alloys, the constituent elements are quite near one another in the periodic table.

Corinthian bronze, is an alloy of copper with gold or silver.

Almost all metals can form amalgams with mercury, the notable exceptions being iron, platinum, tungsten, and tantalum.
