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 n..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom..

The distance from the centre of the nucleus to the outermost shell of an atom is called the atomic radius of that atom (Fig. 2.1..

The negative atom is formed by the gain of one or more electrons in the neutral atom. The number of electrons increases while the magnitude of nuclear charge remains the same. The same nuclear charge acts on larger number of electrons than were present in the neutral ..

To Calculate the Radius of Atom by Making Use of Avogadro's Hypothesis - By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sample of a substance o..

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..

By Avogadro's hypothesis, the actual volume occupied by the atoms in one gram of a substance is 2/3 r d of the volume occupied by 1 gram of the substance. Let us consider a sample of a substance of mass m and volume V. If M is its molecular weight and Avogadro number is N, then Where r = ..

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 taken as eq..
