Chapter 6, Problem 61A

Interpretation Introduction

Interpretation:

The reason for greater amount of energy needed for each successive ionizations of an electron need to be explained.

Concept introduction:

Ionization energy can be defined as the measure of amount of energy needed to remove an electron form an atom or an ion from the outermost shell. The energy to remove the first electron is termed as first ionization energy, Similarly, the energy required to remove the second electron is termed as second ionization energy.

Answer to Problem 61A

The atoms in the core electrons are hold more tightly than those in the valence electrons. Hence, the successive ionization of a particular electron needs a greater amount of energy.

Explanation of Solution

The successive ionization of a particular element needs a greater amount of energy. It is because the atoms in an electron are held more tightly to their core electrons than the electrons in the valence shell. The electrons on the valence shell tend to lose easily as there is less attractive force hence the electrons are held loosely.

Conclusion

The successive ionization of a particular element needs a greater amount of energy. It is because on moving from the valence electrons to the core electrons, the forces holding the electrons are strong.
