thanks to you guys i was able to get a top grade!! Thnk you so much! Your info is so clear and the text and drawings are really helpful to have a visual aspect of it.
Hey Jo that’s amazing well done!!! Definitely due to your time and effort though! Really lovely to hear you’re enjoying the videos though and good luck for all your future work 🥳
I’m a GCSE student and this channel is so underrated. I always come to cognito when I need help in sciences 😅. You explain everything so well (and better than my teachers can). Thank you 😊
THANK YOU SO MUCH YOU DONT UNDERSTAND HOW MUCH THIS HELPED 😂 We’ve been doing this topic for the past term, and i never got what my teacher was on about. school exams in two weeks and i decided to do some revision. THIS FIVE MIN VIDEO TAUGHT ME MORE THAN IVE LEANRED IN A YEAR AT SCHOOL. Thanks so much
This really helps with my style of learning so thank you very much! The fact that they are short videos with pictures really makes it feel a lot easier that it would be if I read it in a book or had someone try to explain it to me. I love how you have a video for every topic we are learning and they are easy to find. Great channel [y]
This is my favorite educational channel! I have been watching your videos from the beginning of the year and I decided to subscribe because most of what I need can be found here❤️
Thanks for this! My teacher just doesn't make sense when he explains this, he always says ''It will make sense later'' but it never does. This really helped, I have a test on this tomorrow and had no idea how to do this before watching the video.
Omg thank u sooo much , I found this channel like 2 weeks ago and it has EVERYTHING that our teacher teaches us🙂Thanks to this is finally understanding What the teacher says
You are an extremely underrated youtuber, you teach everything in very simple ways which are easy to understand and don't complicate things. Every piece of information you provide us with is generally somewhat complex but you manage to deliver them very simply! Thank you for this video and also other ones, do continue what you are doing and help many other fellow students or learners like me! Subscribed with the notifis bell on and also liked! Have a great day cognito and whoever else reads this comment! :) Guys do please pray for me because I have my Chemistry mid-terms tomorrow and keep me in your prayers so that I can pass with flying colors, will keep you all in my prayers too! Thank You! - Farhan
I literally can't thank you enough!!! Ik the creator would prolly not see this comment but I just need you to know that this channel is literally the BEST thing ever!
I still don't get what's the difference between the outer shell diagram, and the dot cross diagram. The one shown in the video as dot cross diagrams, my chemistry teacher calls them the outer shell diagrams and draws something different for the dot cross diagrams.
honestly, before this video I failed my exam twice and felt helpless... After watching this video I got 100% in my exams, I literally was crying and thank you very much. I clicked the subscribed the channel and pressed the bell icon. ❤❤
hi i have a test on this next week and ive been revising so hard and i just can’t understand why some covalent bonds are single, double and triple when they can just all be single. Can someone please help?? ❤️😅
This is because some of these elements have their number of electrons beside them or beside both. They are used to determine how many of the elements are going to be used in the formula or how many elements are going to be shared.
I would love to help u guys financially but we dont have paypal in our country, anyways keep up the gud work i love ur videos and how u explain ur videos are very helpful

I'm an educator, and this is SO WELL DONE!
thank you so much, my teachers show us your videos all the time!
Revising for summerative assessments... This helped, thanks!
this guy just helps it all make sense. is there a video on metalic bonding?
Made it look so simple I’m watching this at 5am I have an exam today and I got to learn this in 4 mins thank you so much
I use this channel for physics chemistry and maths and i use john Campbell for bio. All of this is amazing!!!!!!!
i did a test on ionic and covalent bonding and i got best in my class thanks to you!!! thank you so much
I still don't understand covalent bonding well but this video's helping a little. I've got a full idea of it I guess. Also well done! ^^
Fisr year of chem and this saved my life I passed chemistry thank you ❤️❤️❤️
Amazing. I got better marks because of these videos!😄
Can someone explain to at 1:14 if they are only sharing two electrons then how do they each get one extra?
This is awesome! I couldn't make any sense of these before but now I get everything. This channel is totally underrated.
Ah thankyou Anussukee!! Glad you're finding the channel helpful 😊
so helpful for me, this video cleared all my concepts of this topic
This channel is so underrated!!
I have a chemistry exam tomorrow and I understand this concept so well now!
Thank youuu
Ah thanks einas! glad you're enjoying our videos, good luck with your exam 🤞
How did it go
@@SaintIC it went good!
5:33 @@Cognitoedu
Thank you, this is very detailed and explanatory.

omg sameeee
Your explanation is way better than any of my school teachers
Thanks for the video, what app do you use for making these notes?
You are literally better than my teacher. Thank you ❤
Helped me quite a lot, thank you.
I’ve got exams coming up and I’ve learnt nothing this year bc my chem teacher is useless ur vids have helped so much tysm!
Thanks to this channel i know chemistry very well thank you for explaining very good!!!
I don’t even learn chemistry in english, but this has been more helpful than my own teacher-
I literally can't thank you enough!!! Ik the creator would prolly not see this comment but I just need you to know that this channel is literally the BEST thing ever!
Thank you very much Abeeha!! 😊
@@Cognitoedu haha I'd say thank YOU!! you have earned another sub! 🤪
THANK YOU SO MUCH OMGGG YOU'RE A LIFE SAVER FR
i managed to get a 98 in my chemistry since this lesson was in my finals life saver my guy
just watched your ionic bonding video and they both helped alot thanks you!
Thanks chopsticks 😊
Thank u so much ur so much better than my chemistry teacher!!
I... Actually get this now! Finally feel ready for my exam
Tysm for making these videos, they're SO helpful. im gonna get a top grade now for sure thanks to u. im def gonna recommend your videos to my friends.
Glad you like them!
Did you get a good grade
@@SaintIC Yes I got an A :)
That was a wonderful lesson thank you so much for that it really helped
Oh my word thnx for the help this is much more easier

tysm my teachers are rubbish and you made it so easy to understand im having my ppe's tomorrow you made it easier ♥
IT was very easy to understand. Thank u 🌹🌹
Thx for vid, needed it for chemistry test
he has the same voice as mrwhosetheboss
I was thinking that as well 😂
oh ye I can see it now :0
Omg yesss
thank you so much, my actual teacher is shite and this is helping me understand all of the stuff for my tests. Instantly subbed
Teacher I have a question. So if two atoms of the same element 'share' electrons, then for O3, the three atoms will each share their electron right?
Thanks for the amazing video. Helped me a lot. Much better than my teacher 🤣
I have a question if element is metal it’s positive but if it’s negative it is nonmetal
This is soo helpful !! Thank you soo much ❤
Your videos are helping bro❤️❤️
Thank You So much, You are Very good Teacher And If possible then Upload More videos Thank you lots of Love
Why does sodium nitrate has no brackets?
I still don't get what's the difference between the outer shell diagram, and the dot cross diagram. The one shown in the video as dot cross diagrams, my chemistry teacher calls them the outer shell diagrams and draws something different for the dot cross diagrams.
Do we want to use different colours to represent dot and cross
Like
Dot in blue
Cross in red
Colours
honestly, before this video I failed my exam twice and felt helpless...
After watching this video I got 100% in my exams, I literally was crying and thank you very much.
I clicked the subscribed the channel and pressed the bell icon. ❤❤
Thanks for this, so if there is 2 electrons in the outermost shell, 2 electrons would be shared, am I correct?
yes bro
3:55 what do you mean by just yet he knows something we dont
Great video!
Thankyou so much it helped so much!!
I am loving the lesson 😊
I watched ionic bonding and now I am watching this. Thank you so much for uploading a by which students can easily understand 💜❤️
Thank you so much, I have watched every video of yours and have never forgotten to like it !!! u are the best!!!
Thanks Tyler, really appreciate it!
I have watched every video of yours on the topics I do not understand, and they are always so helpful thank you
Thanks Safia, great to hear!

Thank you so much!! I understand chemistry because of you, teacher! Appreciate it!!💗👍
Ah that's great news 🤩
thank you for this my teacher goes so fast on topics
I guarantee Cognito goes faster
I would love to help u guys financially but we dont have paypal in our country, anyways keep up the gud work i love ur videos and how u explain ur videos are very helpful
Wow amazing lecture. My teacher just doesn’t know how to teach :)
I have an exam tomorrow this is life saving 😭😭😭😭
I’m so fcking done with chemistry
This channel teach me like my teacher would teaches me
Great! whats app did you use to make this presentation?
Thanks! This was made using procreate on the iPad, and keynote on Mac (it took forever I wouldn’t recommend)
Really helpful.
Thank you...
Easily the best channel
Best teacher:)
love this!!!
Really helpful please pray for my good exams
I cant thank you enough. I have a question, when drawing the shell for N, doesn’t it have 7 electrons in the periodic table?
two in its inner shell
Because it is only drawn in it’s outermost shells the other two atoms are not visible. They are located in the inner shell
Thank you very much😊
Thank you so much! What is the software used to create this lesson?
