Lewis Dot Structure For I2

iodine (I₂) Molecule Lewis Construction

Iodine is a diatomic molecule and contains only two iodine atoms. Lewis structure of iodine molecule contains only ane I-I bond and each iodine cantlet has three solitary pairs. It is very piece of cake to describe the I₂ lewis structure.

I_two lewis structure

I2 iodine lewis structure

There is just a unmarried bond betwixt iodine atoms and three lone pairs on each iodine atoms. So, this lewis structure is a very simple.

Steps of drawing lewis structure of I₂ molecule

When we describe a lewis structure, guidelines are given. Number of steps tin be inverse according the complexity of the molecule or ion. Because I₂ is a uncomplicated molecule, it is extremely like shooting fish in a barrel to draw the lewis structure of it in few steps. Even so those all steps are mentioned and explained in item in this tutorial for your knowledge.

Find full number of electrons of the valance shells of iodine atoms
Total electrons pairs existing as lonely pairs and bonds
Center atom option
Mark lonely pairs on atoms
Marking charges on atoms if there are charges.
Bank check the stability and minimize charges on atoms by converting lone pairs to bonds to obtain best lewis structure.

Total number of electrons of the valance shells of I_two molecule

At that place is only one chemical element in iodine molecule. Iodine is a group VIIA chemical element in the periodic table and contains 7 electrons in its last shell. Now, we know how many electrons are there in valence shells of iodine atoms.

valence electrons given by iodine atoms = vii * 2 = 14

Total valence electrons = 14

Full valence electrons pairs

Total valance electrons pairs = σ bonds + π bonds + lone pairs at valence shells

Full electron pairs are determined past dividing the number full valence electrons by 2. For, I₂ molecule, Total pairs of electrons are seven in its valence shells.

Center atom of I_ii molecule

Because, there are only ii atoms and both atoms belongs to aforementioned element, practise not need to worry nigh selecting the center atom.

Lone pairs on atoms

Later determining the middle atom and sketch of I₂ molecule, we can first to mark lone pairs on atoms. Remember that, there are full of seven electron pairs.

There is already 1 bond in the above drawn skeletal. So, there are six remaining lone pairs to marker on iodine atoms.
Considering, there is no middle atom, nosotros can marking remaining lone pairs on both iodine atoms. Each iodine atom volition take three solitary pairs.
Now, all valence electrons pairs are marked.

mark lone pairs on iodine atoms in I2

Mark charges on atoms

There are no charges to mark on iodine atoms in the higher up structure.

Check the stability and minimize charges on atoms by converting lonely pairs to bonds

Because, there are no charges in to a higher place structure, practice not demand to follow this footstep to reduce charges to get the most stable structure. That means, nosotros accept already found the best lewis construction for iodine molecule.

You see, drawing iodine lewis structure is very easy because there are limited number of steps are used.
