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..

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 electrostatic field of an ion is nondirectional.Each positive ion attracts several negative ions around it depending upon its size or radius and vice-versa ,resulting in a three dimensional solid aggregate called an ionic crystal in which oppositely charged ions alternate i..

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 the great..

Three circles of radius( r ) 6 cm each externally touch one another. Tangents at the point of contacts i.e., P, Q, R are concurrent at M. Then PM = => 6 3 cm or 3.46 cm or 13.46 cm or 3.46 3 cm..
