GaI3 Lewis Structure, Characteristics: 17 Facts to Know

GaI3 Lewis structure is represents almost 17 facts regarding the compound. The electronic formation of chemical bond in between Gallium and Iodine and their electron sharing process would be relevantly discussed in this article.

GaI3 Lewis structure is a basic sketch of the shape formed by Gallium and Iodine after sharing their valence electrons with each other where the electrons are denoted by using dots. The facts that would be highlighted in the articles are:

Drawing GaI3 Lewis structure

The drawing of a basic sketch of Lewis structure of a compound follows five strategic steps, which are not exceptional for Gallium iodide as well. These steps are being described below:

Step 1: Calculating the number of valence electrons in each of the elements that is Gallium and Iodine is the first fundamental step to follow before initiating the drawing. The number of valence electrons would be mentioned later in this article.

Step 2: The second significant step is to identify the atom which would hold centre position in the structure. Gallium takes the centre place in gallium Iodide as three Iodine atoms exist around one gallium atom.

Step 3: Third step is to put two electros, which would be partially shared by gallium and Iodine atoms with each other’s.  Those two dots or electrons would be the notation of chemical bond created by the atoms

Step4: The octet (octet rule would be defined later) would be filled with more electrons dots in the next steps. Electron dots would be represented for denoting the lone pairs on the outside atoms and imposing the valence electron pairs on them.

Step5: Calculation of the formal charges is the next step must to follow as this charges helps to identify the stability of Lewis structure of the compound.

GaI3 Lewis structure resonance

Resonance refers to the process of alternating the π bonds with the extra electron present in any atom of a compound. Resonating structures are represented by keeping the chemical formula intact.

In GaI3, there is no π bond exist, therefore; resonance process is irrelevant for this compound and resonating structure also cannot be represented for Gallium iodide.

GaI3 Lewis structure shape

After sketching the Lewis structure of a compound it gives a molecular geometry, which is considered as the shape of that compound.

The Lewis structure of Gai3 represents its molecular geometry by imposing the number and type of bonding. The shape of the compound is determined as Trigional planner.

GaI3 Lewis structure formal charge

Lewis structure of a compound is reliable in expressing the formal charge of overall compound. It significant to notify the number of bond pairs and lone pairs of electrons which are the main component in  calculating individual formal changes.

The formula of calculating formal changes is

Formal charge = Number of valence electrons – Number of nonbonding valence electrons – (Bonding electrons/2)

Formal charge of Gallium = 3 – 0 – (3/2) = 1.5

Formal charge of each of the Iodine atoms = 7 – 6 – (1/2) = 1.5

Therefore, the overall formal charge is zero.

GaI3 Lewis structure angle

The ideal bond angle of Trigonal planner geometry is 120°. This bond angle differs o the compounds having lone pairs. Lone pair – bond pair collision is the reason for giving distinct bond angle to the compounds.

The bond angle of GaI3 is 120° that denotes a symmetrical structure of the compound. zero formal charge and very little amount of of lone pair – lone pair contraction are not enough to provide different bond angle to the compound.

GaI3 Lewis structure octet rule

Octet rule has extensive value in the electron sharing process of preceded by the compounds. This rules refers to the need of electron among the periodic element to fill their last electron energy level with 8 electrons to get ultimate stability as their nearest noble gas.

GaI3 also undergoes electron-sharing process to satisfy their octet state. Gallium needs to 3 electron to stabilise its electronic geometry with 8 electrons whereas each of Iodine atom needs 1 electron to fill octet. There they share their electrons with each other and satisfy octet.

GaI3 Lewis structure lone pairs

After creating chemical bonds with other elements, the overall count of lone pairs of the compound is referred to the number of lone pairs present in central atom.

In Gallium trioxide, it can be easily identified from the Lewis structure that Gallium, the central atom does not possess any lone pair. Not all the valence electrons participate in bonding, which makes sure that gallium, has in lone pair.

GaI3 valence electrons

It is already mentioned above in this article that calculation of valence electrons of the individual elements in a compound is the foremost step to draw Lewis structure of any compound. the number of electrons present in last energy level of a element refers to valence electrons.

Gallium iodide, the metal halide has two periodic element, gallium and three Iodine atoms participates in the formation of this compound. Gallium has three valence electrons and each of the Iodine atom possesses seven valence electrons.

GaI3 hybridization

Hybridisation can be found from the shape of the compounds. The molecular geometry addresses the hybridisation formula.

According to the shape of GaI3, the hybridisation of gallium iodide is sp2.this hybridisation formula is ideal for representing tribunal planner geometry in chemistry, which is possessed by GaI3.

GaI3 solubility

Solubility of gaI3 depends on several chemical and physical properties of the compound. Fusion of two elements induces a specific bonding structure to highlight the geometry of the composite.  The forces for creation of those bonds is the feature which differs the solubility of the different compounds.

How, we can find that solubility of GaI3 is manipulated by its chemical property of binding. Intermolecular force of the hybrid is the main factor that regulates its solubility in any substance.  Gallium triiodide is preferably not soluble in acids organic substances.

Solubility of GaI3 in water

Ionic structure creates difficulties for the compounds to get soluble in water like substances. GaI3 has been recognised as a covalent compound so its solubility in water differs generally.

Solubility in water of GaI3 can be addressed as decomposition. The covalent compound decomposes in water in normal temperature, therefore; it can be accomplished that it is soluble in water.

GaI3 is a strong electrolyte

Hydrated solution of the compounds is the responsible for conducting electricity. In water when two ions dissociate the electrolytic nature of the compound showcased by the ion.

GaI3 readily dissociates in water and gives out Ga+ and I- ions. These ions superiorly conduct electron. Only one condition appears here that is presence if hydrated solution of the compound which drives the decomposition of compound and conduction of electricity.  Therefore, Gallium iodide is a strong electrolyte.

GaI3 acidic or basic

Acidity or basicity depends on the pH level of the compounds. Gallium is a metal with neutral pH level.  Moreover, Iodine atom is the last halogen in periodic series therefore, its acidity is highest.

GaI3 is mildly acidic as it consists of three iodine atoms.   The hydrated solution of the compound produces Ga(OH)3 which participates in metasynthesis reaction with acidic pH level.

GaI3 polar or nonpolar

Polarity depends on the electronic arrangements and the geometric shape of the compounds. Symmetric diagrams indicate zero polarity due to cancellation of tension from each side.

GaI3 has a symmetric geometry, which clarifies the fact that Gallium iodide is a non-polar inorganic compound.

GaI3 a Lewis acid or base

Lewis acid is the element, which contain on of more void orbital for accepting electrons whereas Leis base refers to the substances having extra electrons and that gives away electron to Lewis acids.

Gallium iodide is a covalent compound here gallium and Iodine both the element accepts electrons and shares electrons with each other. Therefore both of the element are considered as Lewis acid and Lewis base.  However, Iodine is more acidic than Gallium and it has deficiency of one electron in last energy level.

GaI3 linear

Linear shape can be defend by mentioning the bong angle of 180° of a compound having two different periodic element. Here one central atom holds only two other atoms in its both side.

GaI3 Lewis structure and its shape from Wikipedia

GaI3 is a non-linear metal halide and it has three Iodine atoms circling around the central atom Gallium. The angle between the bonds is 120°.

GaI3 paramagnetic or diamagnetic

Paramagnetic nature of compound is exposed if any unpaired electrons can be shown to be present in it whereas Diamagnetic a compound have all the electron paired and arranged.

Gallium iodine has all the electron paired and lone pairs on Iodine atoms. Therefore, this compound is clearly a diamagnetic composite.

Conclusion
