81 Tl Thallium

Metal, mass: 204.38 u, 2 stable isotopes (203, 205), abundance rank (earth/space): 64/70

Click image to magnify. 8 grams pure thallium under argon. Original size in cm: 0.7 x 1.5
Thallium Thallium rod
Thallium is a metal which is very similar to lead, but is much more reactive, toxic and rarer than this. Therefore it is used scarcely and only in amounts as small as possible. Poisonings occur by mere skin contact. One application is for special glass.
