How could you determine experimentally whether the compound Ga2Cl4 contains two gallium(II) ions or one gallium(I) and one gallium(III) ion? (Hint: Consider the electron configurations of the three possible ions.)

Interpretation Introduction

Interpretation: An experimental determination as to whether the compound Ga2Cl4 contains two gallium (II) ions or one gallium (I) and one gallium (III) ion is to done.

Concept introduction: Electronic configuration describes the number of electrons in an element and how all the electrons are arranged in each energy level. It is also useful in describing the chemical bonds by which the atoms are held together.

To determine: If the compound Ga2Cl4 contains two gallium (II) ions or one gallium (I) and one gallium (III) ion.

Explanation of Solution

Explanation

The type of ions present in the given compound is differentiated by mass spectrometry. The electronic configuration of Ga is [Ar]3d104s24p1 . With the loss of two electrons, it becomes, Ga+2 . The gallium (II) ions are paramagnetic due to the presence of an unpaired electron.

The electronic configuration of Ga+2 ions is [Ar]3d104s1
