1
Q
Coordination principle; How are the cation-anion radius ratios related to the packing
structure/geometry?
A
It is determined by its relative size
2
Q
Electrostatic valency principle
A
The total strength of valency bonds in ionic structure that reach an anion from all neighboring cations is equal to the charge of the anion
3
Q
Do minerals with uniform (isodesmic) or nonuniform (anisodesmic) bonding have higher
symmetry? Why?
A
Uniform, because the packing is symmetrical
