Where did those electrons go? Decades-old mystery solved
The concept of "valence" - the ability of a particular atom to combine with other atoms by exchanging electrons - is one of the cornerstones of modern chemistry and solid-state physics.

Rydberg atoms are excited atoms that contain one or more electrons with a high principal quantum number. Due to their large size, long-range dipole-dipole interactions and strong coupling to external fields, these atoms have ...
(Phys.org)—In bulk, topological insulators (TIs) are good insulators, but on their surface they act as metals, with a twist: the spin and direction of electrons moving across the surface of a TI are locked together. TIs ...
