← ScienceWhich consequence results when metallic crystal lattice contains vacancies?
A)Increased ion diffusion rate✓
B)Reduced overall material density
C)Enhanced electrical conductivity
D)Elevated tensile strength value
💡 Explanation
Increased ion diffusion is the outcome because vacancies provide sites where atoms can move more easily, implementing Vacancy diffusion. Therefore diffusion increases, rather than options referring simply to bulk properties due to overall changes being too small.
