A small chunk of Thallium in a bottle under oil
Boron group: amorphous brown |b| powder, dark crystalline |b|, a bottle of |al| slugs, |ga| pellets, thick |in| wire, and a small piece of |tl| metal
Small piece of dull gray Thallium metal in an ampoule, itself in a bottle. Despite looking innocent, |tl| is arguably the most poisonous chemical element, even more so than |as|. Even holding this metal is a terrible idea, because it can get through your skin!
