Which of the following statement is incorrect?() The ionization potential of nitrogen is greater(2) The electron affinity of fluorine is greater than(3) The ionization potential of Mg is greater than(4) The electronegativity of fluorine is greater thanthan that of oxygenthat of chlorine.aluminiumthat of chlorine

Answer»

option B , is incorrect.

Fluorine, though higherthan chlorinein the periodic table, has a very small atomic size. This makes the fluoride anion so formed unstable (highly reactive) due to a very high charge/mass ratio. ... As a result,fluorinehas anelectron affinity less thanthat ofchlorine.
