Chapter 4, Problem 4.103QP

Interpretation Introduction

Interpretation: From the given set of properties the property that follows neat periodic trend should be determined.

Concept Introduction:

First ionization energy:

The ionization energy is the minimum energy required to remove the electron from an isolated atom which is in the gaseous state results to give gaseous ion with one positive charge.

${\text{atom}}_{\left(\text{g}\right)}\to {\text{ion with positive charge}}_{\left(\text{g}\right)}\text{ + electron}$

Molar mass: The molar mass is defined as the individual atomic mass of the molecule.

Isotopes: Isotopes of the element differ in their mass number with same atomic number.
