Question

based on the experiment, which of the following is the best description of the sheen of covalent compounds? mostly dull or with very little luster very shiny and reflective silky and glass - like shine metallic with a lot of luster

Explanation:

Covalent compounds generally have low melting and boiling points. They do not have free - moving electrons (unlike metals which have metallic luster due to delocalized electrons). So, they lack the properties that would give them a shiny, reflective, metallic, or highly lustrous appearance. A dull or low - luster appearance is more characteristic.

Answer:

mostly dull or with very little luster
