radius ratio rules for ionic compound

Radius Ratio Rules - For the stability of an ionic compound, each cation should be surrounded by maximum number of anions and vice versa. The number of oppositely charged ions surrounding each ion is called its co-ordination number. The larger is th..

For the stability of an ionic compound, each cation should be surrounded by maximum number of anions and vice versa. The number of oppositely charged ions surrounding each ion is called its co-ordination number. The larger is the size of the cation the greater is its coordinat..

These are radii of ions in ionic crystals. Ionic radius may be defined as the effective distance from the center of nucleus of an ion up to which it has an influence on its electron cloud. In ionic compounds the inter nuclear distance may be t..

Ionic compound AB has NaCl type of structure. If the radius of A + ion is 41.4 cm. (i) What is the ideal radius of B - ion? (ii) If the radius of A + ion decreases and becomes equal to 30pm, then in what type of structure would AB crystallize a..

Empirical formula is defined as the simplest formula of the substance, which gives the relative number of atoms of each element present in the molecule of that substance. Substances which have no discrete molecules such as ionic and network covalent compounds are described by t..

All living and non-living systems are composed of molecules which follow a specific set of physical laws. The molecules found in the living systems are called biomolecules. They are represented by the molecules of about 25 elements of the 109 elements known to exist. Carbon, Hydrogen, Oxyge..

The following rules helps in evaluating t-ratios of the angles: The positive and negative sign of t-ratios of belo..

Results and observations of scientific experiments should be properly recorded under headed columns and numbered rows. The headings must include the units in which each quantity is measured. Graphs are very helpful in comparing measurements. The general rule in plotting the graph of a g..
