Ionic Radii - 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 ..

Being the first elements of each period, alkali metals have the largest atomic and ionic radii in their respective periods. As we move within a period, the atomic radius and ionic radius tend to decrease due to increase in the effective nuclear charge. On mo..

The atomic and ionic radii of group 13 elements are compared to corresponding elements of group 2. This is due to the increase in nuclear charge when one moves from, element of group 2 to group 13 in the same period. As the elements are considered from left to right in the period, the ma..

Elements of groups 1, 2, 10, 11, 12, 13 and some lanthanides form ionic carbides. These carbides react with water liberating lower hydrocarbons. Calcium carbide (CaC 2 ), Beryllium and aluminium carbides (Al 4 C 3 ) and magnesium carbide (MgC 2 ) are examples of ionic..

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 numbe..

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 coordination number..

As we go higher above the surface of the Earth, the value of acceleration due to gravity decreases. But for those heights which are very small when compared to the radius of the Earth, g (and hence mg) can be assumed to be constan..
