Answer:
Explanation:
The concept applied here is the Hume-Rothery rules which tells us the relationships between atomic sizes of solute and solvent , electronegativity, crystal structure and electronic configuration. The rule was named after its founder Hume-Rothery rules.
The solute and host species must have a very SIMILAR ATOMIC SIZES
The solute and host species must attempt to pack with SIMILAR crystal structure
The solute and host species must feature SIMILAR valence electron configuration
The solute and host species must feature SIMILAR ability to attract electrons (electronegativity)
