Problem
Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from left to right in a period of periodic table. Metallic character is inversely related to electronegativity of element.
3N0/2 atoms of X(g) are converted in to X(g)+ by energy E1 , 2N0/3 atoms of X(g) are converted in to X(g)− by energy E2 . Hence, ionisation potential and electron affinity of X(g) are:
( N0 = Avogadro's number)
(1) 3N02E1,3N02E2
(2) 3N02E1,2N03E2
(3) 2N03E1,2N03E2
(4) 2N03E1,3N02E2
