When proceeding down the group in periodic table, the trend in ionization energy has to be rationalized. Concept Introduction: Ionization energy (IE): The ionization energy is the required to remove an electron from an atom in the gas phase. General formula of ionization energy= Atom in the ground state(g) → Atom + ( g ) + e − ΔU= Ionization energy (IE) As predicted by coulomb’s law, energy must be supplied to overcome the attraction between an electron and the nucleus and to separate the electron from the atom. Thus ionization energies always have positive values. An electron father from the nucleus generally has smaller ionization energy and electron closer to the nucleus has larger ionization energy.

Interpretation Introduction

Interpretation:

When proceeding down the group in periodic table, the trend in ionization energy has to be rationalized.

Concept Introduction:

Ionization energy (IE): The ionization energy is the required to remove an electron from an atom in the gas phase.

General formula of ionization energy= Atom in the ground state(g) → Atom+(g) + e−ΔU= Ionization energy (IE)

As predicted by coulomb’s law, energy must be supplied to overcome the attraction between an electron and the nucleus and to separate the electron from the atom. Thus ionization energies always have positive values. An electron father from the nucleus generally has smaller ionization energy and electron closer to the nucleus has larger ionization energy.
