Question

why non metals are non lustrous
​

Answer 1

Answer:

Explanation:

most non metals are not solids and do not have any crystalline surface. In addition they are not able to form a stable or firm flat surface. Normally luster is shown by surface of a solid by reflecting an incident light. Since the non metals do not meet these conditions they are not able to show luster
