Silver :
On the periodic table, silver has the atomic number 47, and it is a transtion metal with the symbol Ag. It has been used from ancient times for a variety of purposes. No one knows how or when silver was discovered, but our word from it comes from the Old English "seolfor." These days, it is used for photographic film, electronics, batteries, and of course, jewelry.
How it typically affects a werewolf:
Silver itself does not kill a werewolf.
Large amounts of silver do, however, or any silver that is mixed in with the blood (i.e. a silver bullet or stake).
If the amount is too small, it will temporarily injure the werewolf, and it may leave a permanent scar.
