Oxn State
Chat i have a doubt during finding Oxn State of an element, cases in which oxn state exceeds valence electrons,
For example of CrO5, its oxn comes out to be +10 while its valence electrons is 6 but since its config is 3d5, 4s1 why is 4s1 included in the valence shell (ik its for more stability)

It pinged twice
dont mind
Anyways guys
sooo
That indicates peroxylinkage
Sorry if you dont understand its
I cant like word it
thick what is the oxidation of o
You end up having -O-O- groups
and then form an equation with oxidation of cr as x and total as zero
and solve voila
Won't work. 1 oxygen is in -2, 4 are in -1
like for this it will bw
I know that but cant understand why is valence shell 4s1 included even if 3d5
well idk par humne vaise hi sikha hai aur sahi aaya tha
I asked my teacher he said that they will explain to us in 12th
+7 hoga as much as i rememeber
I know but
If the valence electrons are 6
f block yes
In its last shell
Why is 4s1 even considered
4s is actually the valence shell. However, when you have incomplete d orbitals, the d electrons can jump to 4th orbit and interact with the outside.
That's why transition elements end up having variable valencies
The d electrons aren't bound by pairing energy, and can jump about
Not as much as the outermost ones, but enough to interact
He said that its because energy loss is for stability
And if its half filled or fully filled more energy is lost due to exchange
About the half/full filled
half filled has lesser stability than fully
and stability and energy has inverse relarion
try thinking with that in mind
structures yaad krle bhai
Lol
CrO5 is butterfly
Jitne bhi oxo acids that are important
yeah
cr3O8-3 is crazy too
You say that, but H3PO3 has resonance structures
i forogor -3 ka
just remembered the basic structure yk
Phosphorus ke acids are problematic tho
thats true
Hypophosphorus polyhypo and all
the nomenclature is all over the place
Oh, no, that's actually really systematic
(n-2)f(n-1)dnsnp all are used as valance shell
🤔 only for a while
this is it. you need the structure
@Brok Bot check out my video on redox. Using strcuture/electronegativity difference you assign oxidation states bond wise
😁
Okay thanks
Bro its all about stability, Taught in f block. Half filled are more stable than partially filled
That's why few element have config like 3d5 4s1 3d10 4s1
in place of 3d6 4s1 and 3d9 4s2
this is taught in atomic structure actualy.
actually*
exchange energy, has to do with quantum mechanics + entropy
The actual doubt is
I cant express it literally or vocally
Neither digramatically
My friend had the same doubt we tried to understand it telepathically
?
they were just the basics then the actual reason comes in
Oh i don’t remember doing anything in f block. But yea the actual reason is not taught in school लोल unless you read Atkins. There too it is superficial.
Right
Yes
Idk man i was always average at chemistry
I could never learn how to balance chemical equations
I still canf
for normal chemical equations hit and trial works for all practical purposes

Balancing Redox Reactions
Oxidation-Reduction Reactions, or redox reactions, are reactions in which one reactant is oxidized and one reactant is reduced simultaneously. This module demonstrates how to balance various redox …
if you can put in the effort to read and revise then chemistry is the easiest subject to get better at
