GCSE Chemistry - Allotropes of Carbon - Diamond and Graphite #18
HTML-код
- Опубликовано: 17 окт 2024
- In this video, we explore the diamond and graphite which are two allotropes of solid carbon and we compare their structure and properties. Allotropes are different structural forms of the same element in the same physical state.
If you’d like to practise the material covered in this video, check out our platform at www.cognitoedu.org - it's totally free, and has been built to make learning and revision as easy as possible. The main features are:
- Lessons organised by topic, only the lessons relevant to your specific exam board and tier are shown.
- Automatic progress tracking. Progress bars tell you what you’re doing well at, and what you need to spend some time on.
- Practise quizzes so you can test your knowledge. You can quiz yourself on any combination of topics you like.
- A huge number of fully-hinted questions that take you step-by-step through some of the trickiest calculations & concepts.
- A comprehensive bank of past exam papers, organised both by year, and also by topic.

Y u lie it’s not free u have to use pro to get unlimited
this is the best gcse revision channel ever, thank you for all your work sir 👑👑
Hi Cognito, I have watched so many of your videos now across all the sciences and even maths I think and I find them unbelievably helpful. They are short and are easy to understand. I think its really admirable that you have made these resources for students (especially across many exam boards as your website is one of the best of the few resources for edexcel igcse) and I think I'm going to ace my coming mocks and then real exams in the summer with your help. Thank you very much
Thank you so much! I am a remote learner and content such as this facilitates me in visualising the concepts! :)

OUR TEACHER HAS BEEN TEACHING US THIS FOR A MONTH AND NONE OF US GOT IT. AND ONE OF MY FRIENDS RECOMMENDED THIS VIDEO. HOW ON EARTH DID I LEARN THIS SO FAST EEEEEEEEEEE
THANKS BESTIEE
If diamond is a giant covalent structure extending in all directions, there must eventually be an edge... What happens to the Carbon atoms at the edge of the diamond - how are their bonds satisfied as this structure leaves several bonds unsatisfied? Great video, by the way, apart from this. Thanks.
That’s probably A level work
Yeah I wouldn’t bother 😂
No thanks
Actually Its most of the atoms of carbon in diamonds that are covalently bonded to 4 other carbon atoms, there is an edge to diamonds and there always will be, the thing is the carbon atoms at the very edge may have reacted with its surrounding for examples...oxygen, CO2 etc. In GCSE this is also knows as oxidation.
@@ulxtrxsvlxtures9598then the co2 must have been diffused in atmosphere revealing the next layer of unstable carbon atoms and the diamond would have been evaporated due to this continuous process.
I had been asking my teacher to explain this to me from months but she did not and you cleared all my doubts in less than five minutes thank youu ❤❤
From india......nice 👍 video
These videos are soooo good for a person of my limited reading ability I get so much for the visual- thank you
Your videos have gotten me through all my work. Hopefully You could add practice questions somehow to test out understanding
that's actually a good idea hope he does
there is the Cognito website, that has questions
you're a star, I am a training to be a teacher to be honest, your videos are so great I learn so much in 5 minutes. Your videos help alot.
I wish u success 💕
If diamond is bonded with 4 carbon atoms and graphite 3 then why did you say that graphite has a spare electron not used in covalent bonding?
you are saving lives broooooo
I love your work :) My students will be here soon, but not yet. Please can I ask you to do a trawl and edit using mark schemes for what the exam boards love and hate in terms of key words. Taking a couple of examples from this video, they would reward shared PAIR of electrons and not award shared electrons. Even worse, they put REJECT on spare electrons and LOVE delocalised electrons. So when I mark papers I think of all the students who revised carefully and then lost a mark for that sort of stuff. Thanks again for lovely graphics and narration.
wait i am just a little confused as you said indivisual layers are held together weekly as there are no covalent bonds between them, but then you said the indivisual layers ARE strongly held together with covalent bonds ?
There's strong covalent bond between carbon molecules in one layer but no covalent bond (Weak Van Der Waal's force ) between one layer to the other
Great video! Could you perhaps do a video about hydrocarbons and fractional distillation soon? Xx
Heya, thanks for that! We are working our way through the course, so we'll hopefully get there mid to late March, but we'll be as quick as we can :)
Your videos are so good, have you got any tips for revising and getting your schedule done, because for me personally it’s very hard to complete a lot💭
Thanks! I would say:
1 - Make a weekly plan of roughly what you want to get done.
2 - Each night make a detailed ish plan for the next day.
3 - Record what you do throughout the day, and look back at it at the end of the day to: a) feel good about how much you've done and b) recap what you've learnt.
Hope that helps :)
Cognito thanks, I will mention you in my videos on my RUclips channel because a lot of people would learn well from you x
@@siobhancheeseman197 Thanks so much!
this video is amazing
thank you very much
Hi, Can I share this video to HK
students, I will specify your RUclips channel in the video.
A very helpful video. Thank you
How does graphite have one delocalised electron?
Because it is bonded to three other carbon atoms, not four.
awesome video! this helped me a lot!! thank you cognito
Army yay!
Wow so helpful. I’m just here because of school though
Thank you sm was so helpful ❤❤❤
in 1:57 you say the individual layers are held together weakly since there are no covalent bonds between them, then at 2:14 you say the individual layers are held strong with covalent bonds, make it make sense!
the layers are held weakly, however WITHIN the layers, the carbon electrons themselves are held together strong with covalent bonds, so the layers are not secure however the electrons within them are secured together tightly.
@@watchamacallit4812 That makes alot more sense, i appreciate it.
Wow amazing🎉
First you said graphite was a giant covalent structure and later u say tht they hav no covalent bond between them...how is tht possible??
The bonds between layers are weak, intermolecular forces, but the forces between the individual atoms *of a single layer* are strong covalent bonds. However, due to convention the whole piece of graphite is referred to as a giant covalent structure, even though in reality, only each layer is a covalent structure. I don’t think I drew this very clearly - hope this explanation helps! - Tom
Thank you Tom it helped!
what are the weak forces between graphite layers called?
weak intermolecular forces

Diamond is graphite blade
Weak Intermolleculuar forces
Vander wall forces
Just saved me thank you 😭
is this in paper 2??
Yep. Paper 2 and 4
THANK YOUU😭
Thank you so much!!!
Thanks
Ty so much
Good
Thanks a lot 👍👍
Allotropes do not have the same physical state actually what makes it differ from anything else is its ability to exist in different physical forms
Thank ya so much dude
Hi this vid is very helpful, can you do a video on carbon fibre or other strong materials
Thank you!
Good vedio
what a guy
very nice vid

Science!
Fuck yeah!
nice helpful
