Question

Under extreme conditions not found in nature, say low temperature solids that are under extreme pressures* prior to collapse into degenerate matter states, does a localized s-orbital radius reduce from its unpressurized solid state?

By localized s-orbital I mean, for example, the 1s² orbital of elements with atomic number beyond Helium.
* found in nature only in high temperature conditions such as stellar interiors

Answer 1

Under extreme conditions not found in nature, the radius of a localized s-orbital can reduce from its unpressurized solid state due to compression and repulsion between electrons.

Step-by-step explanation:

Under extreme conditions not found in nature, such as low temperature and high pressure, the radius of a localized s-orbital can reduce from its unpressurized solid state. When a solid is subjected to extreme pressure, the electrons in the s-orbitals are squeezed closer together, resulting in a decrease in radius. This decrease in radius is due to the compression of the electron cloud and the repulsion between electrons.
