Chapter 23, Problem 66AP

Interpretation Introduction

Interpretation:

The formation of the disodium molecule is to be described in terms of a molecular orbital energy level diagram, and the alkaline earth metals thatexhibit or do not exhibit similar properties are to be determined.

Concept Introduction:

As per the molecular orbital theory, two or more atoms are linked together to make molecular orbitals. It predicts the arrangement of electrons in a molecule.

A molecular orbital energy level diagram consists of the respective energies of atomic orbitals.

The molecular orbital theory consists of bonding molecular orbitals and anti-bonding molecular orbitals. The electronic structure of a molecule is described by this theory.

Alkaline earth metals are shiny and silvery-white with the tendency of losing their outermost electrons to form cations containing two positive charges.

The 1^st group element is also called alkali metals. The electronic configuration for alkali metals is $n{s}^1$. They have the tendency of losing their outermost electrons to form cations with one positive charge.
