Answer 2

Answer:

The bandgap energy order is Diamond>Sillicon>Copper.

Explanation:

Bandgap energy

• The energy difference between the valence state and conduction state of an atom is called its bandgap.
• It is generally measured in electron-volt.
• The conductors will have less band gap as compared to insulators.
• The bandgap order is given as,

              Insulator > Semiconductor > Metal

Now let's categorize the materials given in the question,

Diamond=insulator

Sillicon= semiconductor

Copper=metal

The bandgap energy order of the given substances is as follows,

Diamond>Sillicon>Copper.
