periodic properties
1)Atomic radii:- The distance from the centre of the nucleus to the outermost shell containing electrons called atomic radius.
It is not possible to measure the absolute value of atomic radius of an element.
2)Ionic radii:- The effective distance from the centre of nucleus of the ion upto which it exerts its influence on the electron cloud is called ionic radii.
Anionic radii>atomic radii>cationic radii
3)Ionization potential:- The amount of energy required to remove an electron from isolated gas.
