Get to Know IO3-: Properties Lewis Structure and Uses

I

O3- Lewis Structure

I

O3- is an anion of Iodine that has a -1 charge. To draw the Lewis structure of I

O3-, we need to follow a few steps. Step 1: Determine the total number of valence electrons in I

O3-. The valence electrons of Iodine (I) is 7 which is multiplied by the number of Iodine atoms present in the I

O3- ion, which is 1.

Oxygen (

O) has 6 valence electrons and there are three oxygen atoms present in the I

O3- ion. Adding all these up, we get:

7(valence electrons of Iodine) x 1(Iodine atom) + 6(valence electrons of

Oxygen) x 3(

Oxygen atoms) + 1(negative charge of I

O3-) = 26 valence electrons

Step 2: Write the skeleton structure of the molecule. In the I

O3- ion, the Iodine (I) atom is the central atom. The three

Oxygen (

O) atoms are bonded to Iodine (I) atom through a double bond with other two oxygen atoms, respectively,

O- –

Step 3: Add the valence electrons to complete the octet of each atom. The next step is to add electrons until all of the atoms in the molecule have eight electrons in their outermost shell, except for the hydrogen atoms, which should have two electrons in their outermost shell.

We start with the outermost shell of each oxygen atom and keep adding electrons until there are eight electrons. We add electrons to Iodine (I) atom after that.

Step 4: Check if any atoms lack electrons. In this particular case of I

O3-, the Iodine (I) atom has seven electrons in its outermost shell. It is an odd number which means that it has room for another electron.

But, Iodine (I) can exceed its octet because it is capable of accommodating up to 12 electrons that signify the existence of a d-orbital beyond its valence shell. Step 5: Write the final structure of the molecule.

To represent the odd electron in the I

O3- ion, we can shift an electron from the adjacent oxygen atom to the Iodine (I) atom, generating a double bond. This type of moving electrons around the Lewis structure is called resonance.

O+ –

|| 5 pairs of electrons

Step 6: Check the formal charge of the molecule. Charge separation in a molecule occurs as a consequence of electron redistribution.

The formal charge is the difference between the numbers of electrons on an atom in the true Lewis structure and the number of electrons that it has in the entire compound. The formal charge formula is:

Formal charge = Valence electrons – Nonbonding electrons – Bonding electrons

Formal charges of the atoms present in the I

O3- ion are as follows:

Iodine (I) atom: 7 – 0 – 4 = 3

Oxygen (

O) atoms: 6 – 6 – (4) = -1

The total formal charge should be the same as the charge of the ion which is -1.

Lewis Structure Lone Pairs

In I

O3-, there are a total of two lone pairs present on each

Oxygen (

O) atom, while there is no lone pair present on Iodine (I) atom. The lone pair is a pair of valence electrons that are not bonded to another atom.

The

OI bonding in ion I

O3- creates a dipole where there’s a partial positive charge on the I atom while the

O atoms have a partial negative charge.

Valence Electrons

The term valence electrons refers to the electrons that are present in the outermost shell of an atom, meaning they are involved in chemical bonding. By knowing the number of valence electrons of an element, we can tell what types of chemical reactions they take part in.

The Iodine (I) atom has 7 valence electrons, while the

Oxygen (

O) atom has 6 valence electrons.

Hybridization

Hybridization is the process of mixing orbitals of different energy levels in an atom to form new hybrid orbitals. The formation of hybrid orbitals leads to greater stability and more efficient bonding.

In I

O3-, iodine hybridizes its valence shell s and p orbitals to form sp3 hybrid orbitals that enable it to form 3 sigma bonds with the 3 oxygen atoms of the I

O3- anion. I

O3- Shape and Properties

Shape

I

O3- ion has a pyramidal shape due to the presence of a lone pair on each oxygen atom. When there is a lone pair present on a molecule, it alters the molecule’s geometry.

The molecule’s shape is determined by the arrangement of the atoms and their lone pairs, resulting in the anion’s pyramidal shape.

Pyramidal Geometry

The geometry of I

O3- is pyramidal. Its geometry is affected by the lone pairs present in the

Oxygen (

O) atoms. The repulsion between the lone pairs and the bonding pairs causes the

O atoms and Iodine (I) to move out of the plane, giving it a pyramidal geometry.

Octet Rule

The octet rule states that atoms gain, lose, or share electrons during chemical bonding to attain an outer shell consisting of eight electrons. In I

O3-, the

Oxygen (

O) atoms already have eight electrons in their outer shells, while the Iodine (I) atom has only six. The Iodine (I) atom goes beyond the octet rule and participates in bonding via resonance.

It exceeds 8 electrons by utilizing a d-orbital.

Polar Nature

The I

O3- ion is a polar covalent compound. A polar covalent bond is formed when the electrons are not equally shared between the atoms, causing the molecule to have a positive and negative end.

In the I

O3- ion, the Iodine (I) atom has a higher electronegativity than the oxygen atoms, which causes the

Oxygen (

O) atoms to be partially negative, and the Iodine (I) atom to be partially positive.

Stable Compound

O3- FAQS

I

O3- is an anion of Iodine that has a -1 charge. It is widely used in various industrial applications and has raised several questions about its properties.

In this article, we answer some frequently asked questions about I

O3-. Is I

O3- Ionic or Covalent? I

O3- is a covalent compound. Covalent compounds are formed when two or more non-metal atoms bond using shared electrons.

I

O3- ion is formed by three oxygen atoms and an iodine atom’s covalent bonds. These bonds result from the sharing of electrons between the oxygen and iodine atoms, creating a stable compound.

However, when Iodine and

Oxygen atoms bond with each other, a partial ionic character emerges. Iodine has a higher electronegativity than oxygen, and this results in an uneven sharing of electrons.

The iodine atom pulls the electrons more closely towards itself, causing the oxygen atoms to have a partial negative charge and the iodine atom a partial positive charge. Is I

O3- stable? I

O3- is a stable compound. Stability is achieved when all atoms in a molecule have a complete valence shell of eight electrons or more.

In I

O3-, all three oxygen atoms have eight electrons in their valence shells, while iodine has an odd electron which changes its Lewis structure and gives the anion a negative charge. This odd electron creates an odd resonance structure that exceeds the octet rule and can lead to a potential increase in the bond length between iodine and oxygen atoms.

I

O3- molecules are thermodynamically stable, meaning that they do not spontaneously decompose into their base elements without an external input of energy. They also have a relatively long shelf life compared to other compounds, making them useful in various industrial applications.

What is the polar nature of I

O3-? I

O3- is a polar covalent compound. In polar covalent bonds, electrons are not shared equally between the atoms, leading to their partial charges.

The partial charges can result in a dipole moment, which is a separation of positive and negative charges. In I

O3-, the Iodine atom has a higher electronegativity (the measure of an atom’s ability to attract electrons towards itself) than the oxygen atoms, causing the partial positive charges to accumulate on the Iodine atom.

On the other hand, the oxygen atoms accumulate partial negative charges. This polar nature results in I

O3- having a high solubility in polar solvents, such as water, but low solubility in nonpolar solvents such as benzene.

Conclusion

I

O3- is an anion of iodine that has several unique properties. It is a covalent compound, but it also has an ionic character due to the uneven sharing of electrons between the iodine and oxygen atoms.
