Answer 2

"Metals are usually transparent because of their lack of a band gap: This given statement is false.

This is because, transparency of metals has nothing to do with the band gap. The insulation property of metals is based on band gap but transparency has no connection with it whatsoever.

Pure metals mostly appear transparent, though impure ones can appear opaque too and can reflect light rays through them.
