1.	In thefollowingthe element with thehighestionizationenergy is
Answer» `[Ne] 3 s^(2) 3p^(1)` `[Ne]3 s^(2)3p^(3)` `[Ne] 3s^(2) 3p^(2)` `[Ne] 3s^(2)3p^(4)` SOLUTION :DUE togreaterstabilityof HALF- filled3p- orbitals the element with configuration( b)has thehighestionizationenthalpy. Due tohighesteffectivenuclearcharge , it has thefirstionizationenthalpy. Due tohighesteffectivenuclearcharge , it hasthefirstionizationenthalpy.
