The Table Below Lists the Ionic Radii for the Cations

question 105

Essay

The table below lists the ionic radii for the cations and anions in three ionic compounds.
Each compound has a cubic structure like NaCl, CsCl, or ZnS. Using radius ratios, predict the cubic structure that each compound is most likely to form (that of NaCl, CsCl, or ZnS), the type of holes filled by the cations, and the fraction of holes filled by cations.

Definitions:

Tissue Factor III

A protein that initiates blood clotting by activating coagulation cascade.

Factor VII

A protein in the blood that plays a crucial role in the clotting process, initiating the extrinsic pathway of blood coagulation.

Prothrombinase

Prothrombinase is an enzyme complex that plays a crucial role in the blood coagulation process by converting prothrombin into thrombin, a key step in forming a blood clot.

Thrombin

A protein in the blood that triggers blood coagulation by transforming fibrinogen into fibrin.
