Abstract: We are all familiar with the traditional chemistry of most elements. Except for noble gases, all the elements react with each other depending on the amount of electrons they have in their most external orbital, the valence electrons.

What would happen if environmental conditions, such a large exerted external pressure, forced electrons below the most external orbital to come into play? We believe that in this manner, we can increase the amount of electrons available to form chemical bonding, allowing for the apparition of chemical phases with exotic stoichiometry.

In today’s talk, I will present you the work in progress we are doing in this direction, by means of Density Functional Theory calculations using the VASP program. I will show you that the initial results show how the chemistry of Xe and Hg is changed when they are forced to coexist with F, in different stoichoimetries, atoms under extreme pressures.
