Earth’s core could contain helium from the early solar system. The noble gas tucks into gaps in iron crystals under high pressure and temperature.

Noble gases including helium are normally chemically inert. But under extreme pressures, heavier members of the group (including xenon and krypton) can form a variety of compounds with other elements.

The global hydrodesulfurization catalyst market forecast was valued at $2.64 billion in 2020, and is projected to reach $3.66 billion by 2028, growing at a CAGR of 4.30% from 2021 to 2028.

In compounds they occur as double-atoms, that is e. g. Pr2Cl, and not PrCls and their structure indicates therefore tetra-valency: GROUP O—Noble Gases or Inert Elements: He, Ne, Ar, Kr ...

Heavier noble gases can form compounds at experimentally accessible pressures, but the reactivity of helium – especially below the 350GPa found at the centre of the Earth – was thought to be almost ...
