The essentials

Description 

Here is a brief description of hassium.

• Standard state: presumably a solid at 298 K
• Colour: unknown, but probably metallic and silvery white or grey in appearance
• Classification: Metallic
• Availability:

Hassium, is a synthetic element that is not present in the environment at all.

Isolation

Only a few atoms of element 108, hassium, have ever been made. The first atoms were made through a nuclear reaction involving fusion of an isotope of lead, ²⁰⁸Pb, with one of iron, ⁵⁸Fe.

²⁰⁸Bi + ⁵⁸Fe → ²⁶⁵Hs + ¹n

Isolation of an observable quantity of hassium has never been achieved, and may well never be. This is because hassium decays very rapidly through the emission of α-particles.
