Chapter 12, Problem 12DQ

Interpretation Introduction

Interpretation:Reason for below statement to be incorrect has to be determined.

“Ionization energy for $\text{K}$ atom has negative value because $\text{K}$ loses electron to become ${\text{K}}^{+}$ and achieves noble gas electron configuration”

Concept introduction:Ionization energy represents energy required for removal of outermost valence electron from gaseous atom. It can be represented by I .

  $\text{A}\to {\text{A}}^{+}+1e^{-}$

Electron affinity represents amount of energy released if 1 electron is added to neutral atom.

  $\text{A}\left(g\right)+{\text{e}}^{-}\to {\text{A}}^{-}\left(g\right)$
