Question

What determines the lattice dimensions of minerals? How about their density (specific gravity) resistance to compression (bulk modulus), and melting temperature? Useful inferences can be made using simple relations that describe our understanding of ionic bonding. which is the exchange of one or more electrons between atoms, forming compounds (minerals) composed of positively charged cations and negatively charged anions The attractive force between oppositely charged ions is given by Couldomb's law. The attractive force Fa between the positively and negatively ions is inversely proportional to the distance between the center of the ions, i.e. where q is the charge on the ions and d is the distance between the ions. In ionic solids, this attraction is counterbalanced by Born repulsion, which is produced by interactions between the electron clouds around the two ions, where n is an integer that depends on the number of filled electron shells and Fr is the repulsive force. This repulsive force develops at small distances because the negatively charged electrons around the ions repel cach other Here are properties of some ions that are commonly observed in halide, oxide and sulfide minerals.
