Metals have free electrons, they absorb energy of the light beam incident on them (light as photons) and don't let them pass through . So metals are opaque.

See lessOk I agree with you free electrons are responsible for making metals lustrous or shiny. Suppose we take two same metals :- Case 1:- under bulb Case 2:- under sunlight Of the above two cases where you can observe metal is more shiny appearence and why ?

See lessMetals are opaque, because they have metallic bonding which means that all of the atoms are surrounded by free moving electrons. Therefore, any light that passes through a metal will hit one of these electrons which will absorb the light and re-emit it. The light that is re-emitted is known as refleRead more
Metals are opaque, because they have metallic bonding which means that all of the atoms are surrounded by free moving electrons. Therefore, any light that passes through a metal will hit one of these electrons which will absorb the light and re-emit it. The light that is re-emitted is known as reflection.Hence metals are lustrous.
See lessMetals are opaque because they have metallic bondings meams enough free electrons. All the atoms are surrounded by the fre moving electrons. When light comes ,an electron absorb it and re-emit it also.
