5. Tin resists distilled, sea, and soft tap water, but is attacked by strong acids, alkalis, and acid salts.

Fun Facts:

1. Sn is Tin's chemical symbol because tin is stannum in Latin.

2.Tin is from ancient times so no one knows who or where or when it was discovered.

3.In other countries tin is known as: (see list below)

Isolation: Tin very rarely occurs free in nature. The chief ore is cassiterite (SnO₂). The metal is prepared from cassiterite by reducing the ore with coal. There is normally little need to isolate tin metal in the laboratory as it is readily available commercially. Tin is commonly available as the mineral cassiterite, SnO₂. Reduction of this dioxide with burning coal results in tin metal and was probably how tin was made by the ancients.
