2 Facts

2.1 Interesting Facts

Bismuth metal is soluble and reacts with concentrated nitric acid.

It oxides are used as a yellow pigment in paint. Bismuth chloride oxide BiClO gives a pearly texture to cosmetics.

The most stable isotope of Nobelium metal is No-259.
No-259 has a half-life of fifty-eight minutes.
