Interaction energies of an offset Li atom inside the C N fullerenes (N = 20, 28, 32, 36, 44, 50, 60, 80, and 120) with respect to the radial offset distance η from the center of the fullerenes. Image ...

An atom’s electrons are arranged in energy shells. Like concertgoers in an arena, each electron occupies a single chair and cannot drop to a lower tier if all its chairs are occupied.

Transmission electron microscopy (TEM) has reached unprecedented resolution and can provide structural information down to the single atomic level. It is now shown that a properly designed ...

And, with only three electrons per atom, lithium should behave like a model, simple metal. However, this research has shown that under pressure ranging between about 395,000 atmospheres ...
