Lewis structure of ClO4- ion is attracted step by action in this tutorial. Full valence electrons of offered by 4 oxygen atoms,chlorine atom and negative charge are taken into consideration to draw the ClO4- lewis structure.

Lewis structure of perchlorate ion

There are 4 oxygen atoms and chlorine atom in perchlorate ion.


Now, we space going to learn, how to attract the lewis structure of ClO4- ion step by step. You will learn all steps and also rules that lewis structure drawing.

Steps of illustration ClO4- lewis structure

Following measures are compelled to draw ClO3- lewis structure and they are explained in detail in this tutorial.

just how to discover total variety of electrons the the valance shells
of chlorine and also oxygen atoms and also including fee of the anion How many electrons pairs in valence shells Determine center atom from chlorine and also oxygen atom put lone pairs on atoms security of lewis framework - inspect the stability and also minimize fees on atom by convert lone pairs to bonds to acquire the best lewis structure.

Drawing correct lewis structure is vital to attract resonance frameworks of ClO4- ion.

Total variety of electrons that the valance shells the chlorine and also oxygen atoms and charge that the anion

There are one chlorine atom and also four oxygen atom in the chlorate ion. Additionally there is a -1 as whole charge ~ above the ClO3- ion.

Chlorine and also oxygen are located at 7 and also 6 teams respectively in the regular table. For this reason chlorine has seven electrons in the valence shell and also for oxygen atom, over there are 6 electrons in that is valence shell.

total valence electrons given by chlorine atoms = 7*1 = 7

There space three oxygen atom in ClO4- ion, Therefore

Total valence electrons given by oxygen atoms = 6 * 4 = 24

Due come -1 charge, another electrons is added

because of -1 charge, obtained electrons to valence electrons= 1
full valence electron = 7 + 24 + 1 = 32

Total valence electron pairs

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

Total electron pairs are established by dividing the number complete valence electron by two. For, ClO4- there space 32 valence electrons, so total pairs the electrons room 16. In next steps, we room going to note those 16 lone bag on oxygen atoms and also chlorine atoms together bonds and also lone pairs.

Center atom that ClO4- ion

To it is in the center atom, capacity of having higher valance is important. Chlorine can present valence 7. But, oxygen"s preferably valence is 2. As such chlorine has much more chance to it is in the center atom (See the figure). So, currently we can construct a lay out of ClO4- ion.

Lone bag on atoms

there are already four Cl-O bonds in the sketch. Thus only twelve valence electrons pairs
are continuing to be to draw the remainder of ion. Following step is, noting those ten valence electrons bag on outside atoms (in this case, oxygen atoms) together lone pairs. One oxygen atom will certainly take three lone pairs following the octal dominion (oxygen atoms cannot keep an ext than eight electrons in their valence shells). Therefore, twelve electrons pairs are significant on 3 oxygen atoms. Now, all electrons pairs space finished because of marking on oxygen atoms. So, over there is no valence electron pair to mark on chlorine atom.

Check the security of drawn structure the ClO4- ion and reduce fees on atom by converting lone pairs to bonds

Check charges on atoms and also mark them together below. Dues are important to decision the ideal lewis structure of the ion since in the best lewis structure, charges should be minimized.


The drawn structure for ClO4- is no a steady structure due to the fact that oxygen atoms and also chlorine atoms have actually charges. Also, when charge of one atom (in chlorine atom, there is a +3 charge) is large, that framework become an ext unstable and also cannot be a good lewis structure. When a molecule or ion has so plenty of charges ~ above atoms, that structure is no stable. Now, us should shot to discover a an ext stable structure.

Now, us should shot to minimize charges by converting lone pair or pairs which exist ~ above oxygen atoms to bonds. Therefore we transform one lone pair that one oxygen atom together a Cl-O bond as in the following figure.


Now over there is a double bond in between chlorine and also one oxygen atom. Over there are additionally three single bonds (Cl-O) through chlorine atom and also other two oxygen atoms.

But, there are still charges on atoms and given framework is not steady yet. If possible, we should alleviate charges furthermore. One more lone pair on an additional oxygen atom is moved as a Cl-O bond.


Now, there space twelve electrons roughly chlorine atom. This is acceptable since chlorine have the right to keep more than eight electrons chlorine has actually unfilled 3d orbits.

In new structure, dues of atom are reduced furthermore. But, us can convert one more lone pair on an additional oxygen atom to make an another twin bond. Now you recognize this structure of ClO4- is more stable than previous structure as result of less charges on atoms.

Questions inquiry by students

Ask her question and find the answer free. How plenty of lone bag are uncovered in the lewis structure for the perchlorate ion, ClO4--?

In critical shells, there room nine lone pairs on atoms. There space three oxygen atoms which are associated through double bonds come chlorine atom. Every of those oxygen atoms have actually two lone pairs. Remaining oxygen atom has actually three lone pairs and ceenter atom, chlorine does not has actually lone pairs.

What is the fee of ClO4-

Charge that ClO4- ion is -1. This -1 an unfavorable charge is situated at one oxygen atom.
