- Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.
The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon (14C) is constantly being created in the Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14C combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire 14C by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of 14C it contains begins to decrease as the 14C undergoes radioactive decay. Measuring the amount of 14
C in a sample from a dead plant or animal, such as a piece of wood or a fragment of bone, provides information that can be used to calculate when the animal or plant died. The older a sample is, the less 14C there is to be detected, and because the half-life of 14C (the period of time after which half of a given sample will have decayed) is about 5,730 years, the oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make accurate analysis of older samples possible. Libby received the Nobel Prize in Chemistry for his work in 1960.

History waale raise your ✋ thank you so much sir
Hello Sir I have watched all the videos of chemical kinetics from your channel you explained all the topics very well . Thank you so much Sir !
I request you to make a one video on Transition state theory .
Please reply Sir .
Once again Thank you so much Sir !
Very nice video , really very helpful dear sir 🥰
Nuclear chemistry is very important for BARC examination. It'll be helpful if you make more videos on this topic . Thank you sir
Best explanation.
Sir, please make the video of sub Stoichimetric dilution analysis
Extraordinary........ 👍👍👍👍
Sir geologist nahi archeologist hote hai jo human history study karte hai
Thank you so much sir you are such a great professor your teaching method is outstanding ❤
Very nice lecture sir... I could grasped concept quickly..
Fully detailed... you are intelligent
You are best
You make physical chemistry easy for me
Great explanation . All my doubts are now clear👍👍
I'm students of history honours it is very helpful for me thank you sir
.. my science is very weak but now i understand this topic
Very nice sir thanks
Excellent 👍 explanation sir ji
Owesome sir.too much informative.Allah bless you and your family.many scholar learn from your videos in pakistan.
Bahut accha hai sir ❤🎉🎉🎉🎉apane bahut hi simple fande se samjhaye hai ,ur ha steam ko Hindi mein tree ke jo शाखा or तना or डाल होते है न उसी को कहते है 😅😅😂🎉🎉🎉 एंड थैंक यू सो मच sir
Very nice... Thank you
You are best teacher of the world
I have seen numerous videos on carbon dating... but yes this video is really really helpful..
Nice information
Brilliant sir
super explanation Sir
Sir make a seperate video on neutron activation analysis , isotope dilution analysisand units of radiation
Very well explained
Sir please teach poora nuclear chemistry ka chapter.....It will be so very helpful for my final year exam..
You teach so well
Best 👍
Very good sir class vedio
Supper se v upper
nice video sir
Please make a video about collision theory
In which year que was asked related to carbon dating....in IIT JAM
Bhot aacha explain kra h .
Good
Asslomoalaikum sir g ik vedio how to use radio carbon dating method for estimate age of arganisms
Sir agr hmari body ma carbon 14 ki jagaa carbon 12 present ho toh hm phr kese agr find out kr skte hn? Kindly let me know sir .
Sir agar ho sake to meson theory of nuclear forces pe ak video bana dena please.
You explained ver well sir thank you 😍
Sir ye to bat ho gyi insan ki agar koi utensils ya koi purani things hoti h unka pta kese chalta h wo to nirjeev he usme c14 kese jata he or reduce kese hoga
🤓thank you sir
Thank you ☺️❤️
Thank you so much sir
❤
sir plz explain it on white board
तब क्यो कार्बन दुसरे रसायन के साथ reaction नही करता?
ओर what's minimum age of carbon
Sir please show some good problems on carbon dating
sir ap white board pr explain kia kary
Trying to join your Telegram channel through the link provided in the description box, but it is not assessable.
Numericals based on this topic sir !!!
Sir when we are alive to hmari body se C14 do trah se reduce hoga . 1st by decay and 2nd by C02 formation . Sir is this correct?
very good sir
What is isotope
☕️
Superb video
Thnq so much ❤
Sir make a video on rock dating
Mera ik Question ha... K jb Carbon 14 hm intake krty hai or us k deçy hony k doran jo woh beta decay krta hai or nitrogen ma convert hota hai un radiations sy living beaings ko nuksan niii hota kia??? Or agr nii hota to kia reason hai is ka???
Kisi bhi cheej ka side-effect uske quantity pe depend kerta hai. C14 is very very less in ratio with C12. Hence uske side effect ootne prominent nhi hai.
humy pata kaisy chaly ga k carbon 14 pr 5740 years beet chuky hai
👍👍
Thank u so much sir
Hello
Is c12 ratio to c14 is always same in the nature i mean the ratio before 5000 years and now is it same ??
It changes after some 5000 and above years
Sir can you send your notes on carbon dating
General method of teaching is good.
This method is not so good.
Please come back on old method in which you write with marker. 🌷
Where are you form
Born haryana , living in mumbai
Sir khada hokar kyu Nahi padha the hai
