Atomic Term Symbol (Explained in detail) | All types of problems asked in CSIR

Finding Atomic Term Symbol is one of the most favorite topic of CSIR, I've tried to explain it in detail.

[@salihundatsu1042]

I began to understand this topic after watching your tutorial. Thank you Sir

[@navaldeepkaur9909]

in case of d^2 we cannot leave one orbital vacant like if i fill electron in +2 n 0, filling is wrong. on the contrary in the very next question, you left one vacant orbital in p^4 to get 1^S atomic term symbol. to get this term symbol two electrons are filled in +1 n 2 in -1 orbital. same in d orbital, you said we take negative as positive. but in p we are taking -ve as -ve and +ve as +ve values. which rule to follow? i am confused in the rule followed by you.

[@shayalone7893]

18:14...You filled orbitals with +1 and-1 microstate. Didn't you said we cannot fill like leaving one oribat empty. It violates Hunds rule. So didn't here it's wrong . Thankyou

[@sivan9219]

Sir please explain it

[@riyachakraborty4141]

Same question is mine

[@nikhilsanthosh5602]

Sir, I also have that question. Please clarify

[@sujaltripathi3830]

Go through bret's scheme for p2 and d2 ....

[@sajjadhussain-ee2fd]

sir possible term does mean to fill orbital in differnt microstates like +1 ,0,-1 and to see the term symbol

[@KamleshYadav-lk6ug]

Nice and very catchy exposition sir Ji.

[@niharikachourasiya260]

Sir what will be the term factor for Mn4+ ion

[@kuchv9593]

Sir in the last question, there is possibility of first option also where the 3p electron is having L value 0

[@saptarsikumar3057]

Sir plz tell the possible term in nonequivalent system like s1p1;d1d1 type system

[@chemikamesh4788]

Sir, I have two doubts.. 1. CSIR June - 2017 question, they show p4 "term symbols" are like 1s and 3p but , we are say these are terms only not a term symbol? Term symbol means they give under subscript J value, they dont shown why? 2. half filled means what? confusing

[@mamidiabhishek6809]

18.14...sir u told that... We cannot skip leaving one orbital empty......

[@yogakrishnakumar5431]

Sir, I have two doubts in the last question. Is there a possibility for the single electron to go to the p z orbital ? L+S can be used only when the orbital is more than half filled; in that case is it okay to use that here?

[@AllBoutChemistry]

When it is asked in the question about possible term symbol you've to take all the possibility. In ground state your electron can't directly go to pz and to give L=0, but you can consider that too bcoz here they've asked about possible term. Take that too and see if any of the options you're getting or not. You're absolutely right that L+S is taken when orbital is more than half filled, but then as per the question we've to take all the possibilities. So we've considered it.

[@yogakrishnakumar5431]

Thanks a lot,Sir. As it is asked in the question to find all possibilities we are considering them! I will work out that too and check the answer options.

[@pg-trb-chemneetcsirchem5282]

Thank you sir 💐

[@shaibazchemistry7715]

Why we take out term symbols of elements n wht r it's application in chemistry........ Or it is just mathematics

[@someshchougule181]

Dear sir...aapki aaj ki english aur us samay ki english mein bahut bada antar hai..😲😲 You are gem sir....your today's english fluency is best apart from your chemistry,😀🤩🤩🤩

[@AllBoutChemistry]

Time ke sath hum seekhte hain, time ke sath chize change hoti hain 😊 Thank you 🥰

[@shubhamkale7474]

Sir your explanation is very very nice and my request to you is, please make a video on all the important formulas of physical chemistry and problems based on it.

[@AllBoutChemistry]

Thank you Shubham, I'll try to make video on physical chemistry formulae soon. There are few videos already on physical chemistry you can watch them.

[@gajananshinde7368]

Thanks a lot. Sir you explain concept in very simple language step by step with previous year questions , your all videos giving direct marks....

[@tamannasiddika5744]

Sir apne bola rha ki middle me khali chor ke age ya fir pise electrons fill nhi kr sakte... then apneb1st question krwate waqt middle pe vacant kyu rakha

[@snehasharma9391]

Thank You Soo Much Sir ❤️🙏

[@shallinigupta7207]

As per my doubt sir ... i need to ask one thing that ... In the first example you said weshould consider only 2p4 but in the second last example you took ns1 along with np1 for assigning term symbol. How ?

[@surajthakur401]

Yep

[@swarnalathak5881]

While filling orbitals yu sd orbitals in centr not to be skipped and y is it so in the 1s term?

[@sarmisthapradhan9995]

In the first question 2p4,the term symbol 1s is justified by which filling of electron,is that obey hund's rule?

[@AllBoutChemistry]

I've already said that in question it is asked about possible term symbol so we have to see all the possiblilities (also where Hund's rule violates)

[@navaldeepkaur9909]

@@AllBoutChemistry if all possible term symbols we are violating hunds rule in p4 then why are we not violating in all possible terms for d2 ?

[@soumyaranjandhal6612]

@@navaldeepkaur9909 thats my question also.

[@koushikmitra5224]

Same question from this side also ❓ sir pls can you elaborate about the ২ questions।

Thank you sr

[@Mr.Paul-YT-Channel]

What is the term symbol for p2

[@kishoretanuku8952]

hi sir..which formula is used when orbital is half filled? L-S or L+S?

[@AllBoutChemistry]

At that time use can use anyone of them, as L=0 for half filled

[@snehalshendage]

Very nice explanation sir.....

[@sumitbhatt5712]

Why we leave that orbital while filling e fr possible terms?????????......

[@riyachakraborty4141]

Sir many students asked you the same in 19.05 min you are solving term for 2p4, so for 1S term ,the way you filled the electrons leaving one box in the middle is not it the violation of hund's rule

[@zebanashin1655]

Thank u so much... Such an elaborative and good explanation... 👍👍👍

[@AllBoutChemistry]

Thank you for kind words 😊

[@umendrakhokhar7114]

nicely explained, bro

[@AllBoutChemistry]

thanks brother :)

[@IT-Masterminds]

I had doubt that u say that no gap should not be filling electrons but one of question u did that ...

[@Marthand777]

There are till ways of filling of d2 ?

[@AllBoutChemistry]

Santosh Samaji, plz fill and try to get any of the above options

[@ychemistry2613]

At 18:13 how u feel e by leaving one middle orbital. U said earlier it violets hunds rule

[@chemikamesh4788]

same doubt...I think, the question will ask , possible terms, it means all possible terms, So there should be included of hunds rule violets also possible.

[@aabidhamid5889]

Same doubt. I think it is not violation of Hund's rule

[@subhadipdutta5523]
