Hi I’m a year 10 student and I would like to say that I’m seriously so grateful for your videos because not only are they simple to understand but also very informative and I can’t believe this is all free. This channel is soooo underrated but tqsm for all ur effort :)
Im a year 11 ane I absolutely agree with you it's amazing how it's all free and very informative. Thank you for your efforts and spreading the knowledge to us children helping us through our education and school exams.
The way you get into so much detail to make everything clear. 😭❤ A while ago I was studying and saw Sodium ion drawn by itself with its electrons arranged as 2,8 and I was so confused cuz I thought it was supposed to be drawn bonded with Cl and can only lose an electron to an element. Then I assumed ions existed by themselves without forming bonds. But in here 0:23 you cleared my doubt in seconds! Thank you so much ❤
With videos like these presented in a clear, lucid form, they are easy to grasp and illustrate all the conceptual topics, which is what the science curriculum focuses on in Year 8. Fellow 8th grader here!
This was incredibly helpful so is your website god bless you guys, helped me understand the lessons i found very difficult easily you are a truly talented teacher 💖💖💖
Thank you very much very useful. I was wondering how in depth these chemistry videos are. Are they more to recap key ideas? or are they in depth enough to be everything a student would need to know for the exams?
Thanks Alex! They're made to include everything you need to know for the exams - that said, it is worth doing further reading for deeper understanding, and practising lots of questions :)
hi! as someone who watches your playlists for every science, ive started using your website too! if possible could you just upload every slide of info from your videos for each unit? i think it would be a helpful addition for anyone who wants to look at a very specific point!
Hello. Thank you for the video it was very useful and easy to follow. But I have a question I couldn't find an answer to: So, if the charge of a Catbon atom is 4+ and the charge of an Oxygen atom is 2-, in order for them to be stable, one Carbon atom would need to form an ionic compound with 2 oxygen atoms. But why is the formula for a Carbonate C03? I understand it's because it has 3 oxygen atoms and 1 carbon atom but if all a carbon needs to be stable is 2 Oxygens, why is the 3rd one there? Sorry for grammar English isn't my first language 😅
Great video! i have a question: Chlorine reacts with aqueous FeCl2 to form a FeCl3 solution. Write a balanced ionic equation to show this reaction. (3 marks) could you please explain how you would get to the answer? Thank you.
Bit late but for anyone interested: Cl2 +FeCl2 -> FeCl3 Now to balance it: Cl2 + 2FeCl2 -> 2FeCl3 And with state symbols for higher tier: Cl2 (g) + 2FeCl2(aq) -> 2FeCl3 (aq)
Hey Cognito, wouldn't it be easier to use "Criss-cross" method to show ionic compound's formula rather than using "LCM" method? I personally feel that the Criss-Cross method is easier to use... Like if you agree...
i've seen ionic compounds being called lots of different things like a giant ionic lattice or a giant lattice structure but then here it says regular lattice structure, can it be called anything like that?

I agree
i too am a yearr 9 student totally agree with u these videos are clearer than our schools explanation from zoom
bro teaches way better than my own science teacher THANK YOU FOR SAVING ME IM ON THE VERGE OF TEARS I SWEAR, you deserved a subscriber which is me
used to be so scared of chemistry physics etc but now I’m actually understanding and becoming interested!! Lmao tyy
same

Okay let me just say that the drawing part completely filled all of my questions about ionic compounds so thank you sensei😭🤧
Why u call him Sensei that a bit sus 😑
@@ryze5436What do you mean??
@@sunvequiano3740 I was joking around
thanks for letting us know
i think she was in a goofy mood 🤪
Learnt more from Cognito than I ever did from my actual chemistry teachers over the course of ~4 years.
Thank you your teaching method is very nice❤😊❤😊
Who else watching this the day before exams?.
I have finals tomorrow 😢
I'm watching it the day of
You are carrying my chemistry grade. words cannot express how appreciative I am Thank you
Well we really appreciate you taking the time to comment, thanks Malak 😊
I'm new and I have to say...
THIS IS AMAZING! I LOVE THE EXPLANATION! IT'S VERY CLEAR AND SIMPLE! THANK YOU SO MUCH 💜

@@studentWatches lmao
Your videos shows a concept maps which is one of my tactics to understand your videos!! I'm thankful!!
legit so helpful dude thanks
you deserve more views. f the youtube algorithm
Haha thanks Clara! To be fair comments really help bump them up the algorithm so thanks so much for leaving one!
Thank you for all your videos, they really do help!
Glad you think so, thanks for taking the time to let us know!
@@Cognitoedu No problem, I should be thanking you. Your videos + freesciencelessons are a really good combination. Where's your accent from btw?
Cheers, well i'm from the midlands, but lived in Australia for a few years
thank you! your videos really help me understand science. commenting for the algorithm, you deserve more views :D
Aw thanks jelly comments like this really do help, we appreciate it a lot 🤩

thank you!!! this helped a lot!!!
I'm really learning alot🎉🎉🎉
Thank you very much. I did not understand the lesson and now I understand it
🙏🏻❤️
Actually I've used your teaches for my research 😄😄🙏🙏❤️❤️
ty i have short trem memory and dyslexia so this helped me a lot, im confidient that ill do good on my test now ty
year 9
Ah that's great, hope the test goes well 🤞
Great video! This topic is very confusing so thanks very much!
Thanks Timber! We're glad its making a little more sense now 😁
Thank you so much for these videos.
Shout out to my chemistry teacher who made a point of explaining this when I was in the bathroom
Very informative
Thank you very much
Thank you so much, this helped me so much
Love your efforts man
Amazing 🔥
thanks,
this was really helpful👍
Awesome video. :) Where do you get all these facts from? GCSE CHEMISTRY syllabus? or textbooks? or Wikipedia or some science site?
1 Month before Y11 mocks, and i'm only just understanding it now
lolol same-
I’ve got mocks coming up too 😢
thanks, really helped
I am in 7 and this really helps.
Thanks a lot
revise for gcse now

@@pushparadhakrishnan7343 How do you get that? I'm really confused...
Im in sec 3 and this is helpful for last minute
I just want to ask a question, these videos are really helpful, but what do you use to make them.
Microsoft animations
thank you this helped me alot
It really helped sir
ploughing through before my chemistry GCSE today💪🏻.

Like if you agree...
I am two year in ten class thanks for helping.
Thanks👍
This. Hannel is a blessing i hope it doesnt become payed in the next few years . U guys afe saviours btw i tried you website and i loved it
Task completed!
This is amazing thank you so much
And you still give hearts 2 years later.. legends!!
Hello, I found these very helpful. Are there A-level chemistry as well?
Very helpful
2 days until my mocks thank you
so how'd they go?
@@muhammadafaqahsan6143 good
who else's teacher sent them here
Mine lmao
Same lol
my teacher used this video in his lesson lel thanks cognito!
Would the formula for cation and anion of an compund be the same?
If not then how would we take that out?
Im a year 6 and i shouldnt have watched it but thanks for the extra info
brooo thanks
i've seen ionic compounds being called lots of different things like a giant ionic lattice or a giant lattice structure but then here it says regular lattice structure, can it be called anything like that?
hi thx for the vid
Good
Wow just wow
Nice
calcium hydroxide should Ca(OH)2- right?
hi , how would we know which topics are specifically just for triple science
Am very weak at chemistry in formation of ion and cation would you do me a favour sir
I have a question
Question: what is lattice energy?
When you eat lettuce
A lattice is formed when metals form a very complex structure
Please give me the formula for hydrogen carbonate
🤩
Thnx which country are you from.
Why u wanna know that??
Alexa play "Make No Sense" by NBA Youngboy. Not your fault though great explanation.
Its sodium chloride
I’m not watching a 6 bludclart minute video
😮
I wonder if anyone that's watching this in my class rn can see this comment?
i still dont get it chemistry is a hard one
The guy narrating this sounds like a really bored lazar beam
I don't hear it
and an english one
Frr
Friesen Isle
the only topic even cognito cant explain to me (I hate ion topic bro I'm stupid at it)
