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 the size of the cation..

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 ..

The atomic and ionic radii of alkaline Earth metals are smaller than the corresponding members of the alkali metals. This is due to the fact of Group 2 elements having a higher nuclear charge allow electrons to be attracted more towards the nucleus. This reduces the size of atomic and ..

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..

What is the ratio of the surface area of a sphere with radius 1 in. to the surface area of a sphere with radius 2 in.? => 3 : 2 or 1 : 5 or 1 : 4 or None of the above..

What is the ratio of volumes of a cone of radius 28 cm and height 42 cm to a cylinder of radius 7 cm and height 14 cm? [Take π = 3.] => 16 : 1 or 22 : 1 or 21 : 1 or 24 : 1..
