Answer:
Tin and Copper
Step-by-step explanation:
The two atoms that could potentially form alloys are the tin and copper atoms.
Alloys are mixtures formed between two or more metals.
The goal of forming alloys is to take properties of one metal and add to that of another metal so as to enhance both materials.
Alloys are only formed between metals.
The only metal pair given from the choices is that of tin and copper.
Therefore, the two atoms that could potentially form alloys is tin and copper.
