Physical and Chemical Characteristics

?? Origin of the name:
Middle English: "ambre"
Middle French and Medieval Latin: "ambra",
Arabic: "anbar ambergris"
It is very curious that the Greek name for Amber is: "electron"
Around 600 BC, Greeks found that by rubbing an electron (Amber) against a fur cloth, it would attract particles of straw. For over 2000 years this strange effect remained a mystery. But in the 1600's, Dr William Gilbert investigated the reactions of amber and magnets and first recorded the word 'Electric' in a report on the theory of magnetism.
Isn't it interesting that the words "Electricity" and "Electronic" are related to this beautiful gemstone?
