Atomvolumen, Packungsdichte und Wertigkeit von Caesium unter Druck
Atomic volume, packing density and valence of Cesium under pressure
- The volume changes of cesium under pressure are discussed with respect to the packing density of the atoms and valence. The element is univalent in densely packed Cs I and Cs II. Valence increases in Cs III (packing density q = 0.973), in Cs IV (q = 0.943), in Cs V (q ~ 0.99), and in close packed Cs VI. The diminuition of volume beyond ~ 15 GPa is caused by this increase only which implies that electrons of the fifth shell act as valence electrons.
