Sir I love your lessons. There has never been a time where your explanations fail to clear something up for me. Thank you so much!
my book says 4s has the 29th electron of copper, is it correct? Kindly answer
@@nimrabaloch12 yes
@@dheerp9471 how?
No, it's not 29 is the valance number. But don't forget that :- S=2
P=6
D=10

Hey man just wanted to let u know that u helped me alot in many exams keep up what you are doin
In class: complaining that the teacher gives too much work.
Quarantine: complaining that the teacher gives too little to work with.
Agreee
No stupid face, pleasant voice, calm, formal, logical. great presentation.
Thank you so much for your hard work ,the lessons really helped me in my exams ,and one can focus better during quarantine
I searched in all my books but didn't get the actual reason for this exception (one of my teachers told once told the reason but I forgot 😩)
Thanks for this information 👍👍
hybridization
The exception is due to purely quantum mechanical effect which isn't intuitive and complicated. It's called spin correlation or spin exchange stabilization.
Simply put there is an integral that involves the spin wavefuctions of the electrons as part of the energy of the configuration, having the same spin lowers the overall configuration energy relative to others.
Even more simply because of Quantum mechanics hanging out with electrons with the same spin lowers your energy.

Professor Organic Chemistry Tutor ,thank you for another beautiful video/lecture on Electron Configuration Exceptions in AP/General Chemistry. The two examples are really helpful for all current and future students who are taking AP and General Chemistry. Two other Electron Configuration Exceptions are Molybdenum(Mo) and Silver(Ag). This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
Sir frankly I nor any other can stress this enough...your amazing at this, thanks 👍🏾
this made it so much easier to understand, thank you!!
i love you
u are amazing ur the only reason i can pass chemistry
Thank you so much. My classmate refer me to this channel. Thank you to both of you.
I love you Organic chemistry tutor. You are cool with everything.
Thank you so kindly for your videos. You are amazing teacher. I have learned a lot from you. Also, I am able to comprehend chemistry better because of you. Thank you, thank you, & thank you.
The other day l scored 80 percent in chemistry after watching your videos .l didn't even looked at my lectures notes.
You make this things look more simple.
i got a test tomorrow 🙏
going back with concepts...just loved the video. ❤
You helped my out on polar coodinates and stuff years ago and im still subbed xD
is the exception same (unpaired tendency) in CU too? cuz the d subshell is fully filled and they are paired now? why did one electron go from 4s2 to 3d9?
Guy let consider supporting him and other people like him on Patreon. They devote a lot of time to help us.
Thanks you’re saving me.
Why does the electron jump in Copper? There isn't technically any "open space" there like it is in Chromium...
The real reason isn't about jumping or having room or stuff ..it is because , it is easier for them to remove a 4s electron and bring it to the 3d subshell, which will give them a half filled or completely filled subshell, creating more stability.
@@lunam11 so for a Cu+ ion does the 4s1 electron get removed first? As it’s easier to remove due to its lower energy?
tell me what is the reason why it doesnt work by aufbau principle?
Cu-3d10 4s2
Cr-3d5 4s1
Ag-4d9 5s2
Pd-4d8 5s2
Cd-4d10 5s2
La-5d1 6s2
mam plz reply it is right or wrong
You saved my atomic m-ass
but the real question is why does it do that only at those two times, why not at others like titanium
It’s probably because it’s more stable that way. In Cr and Cu case, the electrons leans towards to being unpaired because of its repulsion(?). maybe
Because after filling the titanium it will be not completely fill
It's nice video. I'm wondering, can we say the condition that electron move from 4s to 3d is an excitation state? So, what is exactly electron in 3d at ground state? Thank you, anyway 🙏
THANK YOU SO MUCH I WISH U WERE MY CHEM TEACHER
this does not make sense
because the copper is getting a pair
and you said they didn't like to go in pairs...
can you please tell the real reason the behave like that???
because it is easier for them to remove a 4s electron and bring it to the 3d subshell, which will give them a half filled or completely filled subshell, creating more stability.
Is this for only copper and chromium??
Yes
Thank you!!! Finally understood!!!
But what if Copper has a positive charge, like +1?
Thank you sir.
Cool ! Now i understand
Are Molybdenum and Silver are chopped liver to you?
Great work tr now I've understood
Thank you
Magnificent,,, it's done
very helpful thank you.🤩
Very good and mind blowing
Why cu show+1 oxidation state but cr can not??
Kindly reply me
Are there any other exceptional elements in the whole periodic table like these?
The 2nd transition metal series also have irregularities (yttrium to silver)
@@darkmathsamport3694 there are some people that say it's even possible for carbon 😭
Bro just saved my life 😂😂
thank you
Sir my book says 4s has the 29th electron of copper, is it correct? Kindly answer
* me binge watching the organic chem tutor in my first few weeks of form 6 *
Thanks sir 😁😊
Thank you!!! This makes so much more sense now!
Why does it only apply to these elements?
Sir, then why dont we write the same for carbon, silicon...etc
Are Cr and Cu the only exception?
Cu and Ag, they will borrow one electron from the s orbital to make it full. But these are the two main exceptions that will appear on test.
@@dariensalomon6672
Thanks so much 🙂❤️
@@lunam11 and Mo
5:34 Is it really correct to call them "exponents"?
TOCT is da GOAT
Thank you sir...
Thank you sir
Thanks, bud.
what about the lanthanides and actinides?
When I counted d orbital the total electrons are 9 why
can this apply to carbon?????
C is not an exception
yea sure man
yea
agreed
Thanks you a lot dude
God!.. Thanks🥃❤️
I didn't understand ... Please could anyone help ?
is it need to change 4s1 3d10 to 3d10 4s1?
it is not need but you can also do it in that way
thank you !!
Respect ☑️
Thnkss broda
thanks man
Wow.
The only configuration I had a doubt in was Copper in the first place and the guy didn't even explain that smh
Who no coments on some of your vides?
Am I the only one who has never seen his face?
He should do a face reveal.
there is no topic or subtopic this guy has not covered
This is called anomaly.

@@kelvinmubanga8938 how though? 19th electron is present in 4s?
