What is the Lewis structure for XeH4?

The Lewis structure of XeH4 consists of a single xenon atom at the center of the molecule, surrounded by four hydrogens. Each hydrogen has a full shell of two valence electrons, leaving a total remainder of 12 to attach to the xenon atom.

The Lewis structure of XeH4 is unusual among molecules, as the xenon atom at its center supports more than the eight valence electrons of most of the elements in its period. The extra carrying capacity of xenon allows a stable placement of the extra four electrons around the molecule's central atom without upsetting the formal charges of the structure.
