Lithium Metal (Li)

Animation (3x3x3 Lattice)
Book Figure

Animated rotational perspective of a lithium metal lattice with transparent electron planes. The electron planes behave as mirror-image negative point charges to the Li+ ions such that the metallic crystal lattice bonding is Coulombic in the same way as that of an ionic compound.

Alkali Metals (Li, Na, K, Rb, and Cs )

Book Figure

To-scale structure of unit cells for (A) Lithium Metal; (B) Sodium Metal, (C) Potassium Metal, (D) Rubidium Metal, and (E) Cesium Metal.

Calculated and experimental values for the lattice parameters and lattice energies for the metallic bond of alkali metals. Calculations are made from exact, closed-form equations containing physical constants only.
