The Solid State

Four interactive labs for the Solid State chapter — rotate the lattice, derive the result, lock it in. Built around the JEE & NEET syllabus.

SC · BCC · FCC · HCP
— packing, coordination, derivations.

Tetrahedral & octahedral voids,
the radius-ratio rule.

NaCl · ZnS · CaF₂ · antifluorite
— fill the voids.

Schottky · Frenkel · F-centres
· non-stoichiometry.
