☝ Chemical periodicity Atomic radii Atomic radius means the distance from the centre of the nucleus to the outermost shell of electrons. But absolute size of an atom is difficult to be defined because of the following reasons: (1) atom does not have well defined boundary . So probability of finding electron is never zero even at large distances from the nucleus. (2)it is not possible to isolate an atom   and measure it's radius. the probability distribution is also affected by presence of other atoms in its neighbourhood. We can only arbitrarily define Atomic radius as effective size  which means the distance of closest approach of one atom to another atom in a given bonding situation.   Atomic radii may be called as , covalent radius, Van der Waal's radius , ionic or crystal radius, etc depends upon the types of bonding. Covalent radius One half of the distance between the centres of nucleii of two similar atoms bonded together in a molecule. For example :- the int...
