Chapter 12, Problem 2STP

Interpretation Introduction

Interpretation:

The correct option concerning the trends on periodic table is to be chosen.

Concept introduction:

Ionization energy is energy needed to remove the valence electron from isolated gaseous atom.

Electronegativity is the tendency of an atom to attract shared pair of electrons towards itself in a covalent bond.

Answer to Problem 2STP

D

Explanation of Solution

On moving left to right, atomic size decreases and value of ionization energy and electronegativity increases. Therefore, smaller atoms have larger ionization energies and larger electronegativity values.

Conclusion

Option D is correct because on moving from left to right in a row, ionization energy and electronegativity increases.
