3. Which two atoms could potentially form alloys? Tin and Copper
Bromine and Potassium
Sodium and Chloride
Hydrogen and Oxygen

Tin and Copper

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.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
