History and Discovery

We are not exactly sure when tin was first discovered but we think it was discovered around 2100BC. Since we are not exactly sure when tin was discovered we don’t know where or how tin was discovered. We are not sure who was the first person to discover tin because it has been around for a while but we do know that Chinese were mining tin and a tin ring and bottle were found in and Egyptian tomb so they must have been using it.

Applications and Uses

Tin is mostly found in an are called the "Tin Belt" which goes through China, Thailand and Indonesia. Tin mining occurs is Bolivia, Peru and Brazil. It is used to make cans for canned food.It is used to coat other metals to prevent corrosion. Tin is also used in chloride as a reducing agent and it is used as a mordant for dyeing calcio and silk.

Tin has 10 different Isotopes. Most of them are stable except 124Sn. The other isotopes of tin are 112Sn, 114Sn, 115Sn, 116Sn, 117Sn, 118Sn, 119Sn, 120Sn, 122Sn, and 124Sn.

Bronze is an alloy of copper and tin. Tin and lead were alloyed together to make pewter and solder. Another alloy that tin has is tin and niobium. This is used to make super conductive wires.

Name and Symbol

The name comes from the Anglo-Saxton word tin but tins symbol comes from the Latin word for tin, stannum.

Fun Facts

TIn compounds have been known to be used as anti-fouling paint for some ships and boats which prevents barnacles.
