1. Describe how ultraviolet light degrades plastics and why it does not generally degrade metals.

Step-By-Step Solution

1. Ultraviolet (UV) light interacts with the electrons in covalent bonds, often raising the energy of the electrons so they are no longer in a favorable bonding energy level. When this happens, the bond is broken. This rarely occurs in metals because the energy of the sea of electrons can be excited with little effect on any individual bond between the atoms. Hence, the bonds remain intact even when some of the electrons are excited to higher energy levels.
