Allotropy of Iron: Thermodynamics and Crystal Structures …
As some lattice distortion must take place when carbon atoms enter the iron lattice and which thus, does not allow large solid solubility’s of carbon in iron. In FCC γ-iron, octahedral holes are large sized than tetrahedral holes and thus carbon atoms sit in these symmetrical octahedral holes even though some uniform lattice expansion takes place.
Calcium Carbonate - University Of Illinois
Calcium carbonate, CaCO 3 Calcite is one of the most abundant of the non-silie minerals. Pure calcium carbonate is colorless but, because it dissolves in acidic water and can recrystallize with different inclusions, calcite has many forms and colors in nature.

Lattice Energy - Decomposition of Group II carbonates The ease decomposition of Groups II carbonates is determined mainly by the size of the metal ion. The smaller the size of the ion the more polarizing the ion is. That is, the metal ion interacts with the electrons in the carbonate ion, destabilizing the bonds leading to the formation of the metal oxide and carbon dioxide gas.

Which one of these diagrams represents a pure metal?Diagram b is a pure metal – the atoms are arranged in a regular lattice. Whenpressure is applied (by hammering the metal) the layers can slide over eachother – this is why metals are malleable and ductile.But when the metal is an alloy (diagrams a, c, and d) new atoms enter thelattice and the layers can no longer slide easily.
