ionic radius is smaller than its atomic radius

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 s..

The distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the atomic radius of ..

The distance from the nucleus to the outermost shell depends on the electrostatic attraction (nuclear charge) that the nucleus exerts on the electrons of the outer shell. More the nuclear charge closer are the shell and electrons, hence smaller is the atomic radius of ..

It is defined as the distance from the centre of the nucleus upto the last shell containing the electro..

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..

A cation is formed by the loss of one or more electrons from the gaseous atom. Thus, the whole of the outer most shell of electrons is removed resulting in the smaller size in the cation. For example, in lithium atom, there is only one electron in the outermost '2s' s..

The atomic and ionic radii of group 15 elements are smaller than the atomic radii of the corresponding group 14 elements. This is because of increased nuclear charge. On going down the group, the atomic radii increase due to the increase in number ..

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..

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..
