AQA A-Level Chemistry - Ionisation Energies 

My chemistry teacher is great. But you my friend are a legend.

WE LOVE YOU RINTOUL, WE DO WE LOVE YOU RINTOUL, WE DO WE LOVE YOU RINTOUL, WE DO OOOOOH RINTOUL, WE LOVE YOU

YOUR VIDEOS ARE SO AMAZING!! I AM STRUGGLING SO MUCH WITH CHEMISTRY, AND YOU'RE SAVING MY LIFE! Your videos are brilliant! Keep up the good work :) Thank you so much!

The videos from 8 years ago are really helping. Thank-you so much

I could barely focus in winter break due to external things occurring in my life, the lack of knowledge only making everything more stressful and generally worse. As I sit and watch your videos in order to take last minute revision notes for my upcoming mocks (directly after winter break), I simply cannot thank you enough for making a subject so daunting seem bearable and even enjoyable at times. Super glad my classmates exchange your videos, thank you so much!!

Could you please finish the whole AS course because you method is so perfect????

This is really helping! I've got my unit 1 exam tomorrow and have been watching these over the past few weeks to bulk up my revision but you explain things a lot better than how one of my teachers does, we've been expected to teach ourselves, but yeah I've learnt a lot more watching these! Thank you!

Your videos are so helpful!! I'm in year 12 and I've been struggling in chemistry for weeks but the way you teach it makes so much more sense. Thanks for making these videos, these are going to be my new revision method. 😊

+Rumanaa Rulezs Thats my method of remembering diatomic elements I Iodine Have Hydrogen No Nitrogen Bright Bromine Or Oxygen Clever Chlorine Friends Fluorine

Can't emphasise how useful these videos are. Thanks so much!!!!!!

best lesson of last minute chem ever considering i have 7 days till the exam and don't know what i am suppose to be doing this has helped by A LOT

All of your videos are fantastic as you explain everything so well!! You are really helping me get through AS Chemistry and I find all the exam questions you do extremely useful. Thank you so much! :)

omiGOSH THIS IS THE ONE VIDEO AFTER WATCHING 20 VIDEOS THAT I ACTUALLY UNDERSTAND AND GET IM SO LATE LOL 3 YRS BUT BLESS WHOEVER MADE THIS

So happy I found ur videos!! just started As chem a month ago and needed a bit of help and I found ur channel!! :D it really helps

I must say I've watched a few of your videos, and they're really helpful for revision. We did Ionisation Energies about 5 weeks ago and I was okay with it, but having watched this video its really clear now and hopefully I can smash it in the exam. Thank you so much!

God bless you mate, Absolutely straight and to the point explainations you have given here. Thanks for the help!

Thank you for taking the time to doing these videos. Very helpful :)

My chemistry teacher recommended you and you are amazing thank you soooooo much.

These videos are so helpful thank you!!

All your videos are amazing! The way you teach over a video is so much useful than my chemistry teacher. So thank you so so much!!!:)

I've been really struggling with A level chemistry but your video's are so helpful, thank you!

Your a life saver, thanks man.

Your videos are so so helpful thank you for everything! :’)

WOW THANK YOU SO MUCH! I was in class today and SOOOO confused and I actually understand it now in 20 mins!

Imagine getting 40k+ subs without a profile pic

We appreciate what you are doing

Best Channel Ever.

Any chance of posting one about electronegativity? Really helpful videos, good to have as it is extremely hard to write notes and listen at the same time.

Man, thanks so much for this video! The training materials I'm meant to be learning from pale in comparison to your explanation!

Thanks for another great video!

Thank you so much! I hope you keep doing these :)

Thank you soo much! This is great for revision :)

Thank you such a massive help !!

your videos are amazing

Still HElpfull thank uu so much

life saver thank you so much sir

I don't take A Level chemistry. but I take applied science btec and this is the first chemistry topic covered. I cannot thank you enough for going over this dude :)

GREAT Explanation!

You are an absolute god send!

Thank youu, you saved me from failing!❤

this is so useful 😅 thank you!!!!

Thank you very much, Sir.

thank u, i have a really good teacher but he uses more scientific words that i do not understand so... in a way, than u for this video!

You are amazing.

goodluck to #TeamERintoul for tomorrow!

Have you added any video on mass spectrometry?

You sir, are a legend!

thank you for the lesson

the best teacher

You're a god send! Thank you!

This was such a good video!! 😂😂😂🎉🎉🎉🎉❤❤ Thanks sir!!

Do you have any videos that go into detail about the different stages of the mass spectrometer and identifying which species is responsible for a certain peak? Would be very helpful. Thanks :)

Very very well expleinedy

Thank You!! you really have helped me so so much!! :) However, i have i quick question from the jun2013 paper that im really struggling to understand - its question 5g 'Which one of the first, second or third ionisations of thallium produces an ion with the electron configuration [Xe] 5d106s1?'- i dont understand why the answer is second, because the jumps from 81 to 65, so wouldnt that be like the 16th ionisation energy? if that made any sense :S

😄 Brilliantly explained

Mums life you acc good like Thank you! Way better than my Teacher in terms of explaining the concept

This video taught me more in 20 minutes than my teacher in 2 hours

Sick one bro

thank you !!

Thanks sooo much!!

Amazing!!!

hey rintoul can i use this notes and techniques for cie a level examinations? is cie and aqa same?

I'm doing AS WJEC Chemistry and this is brilliant work. Wish he could do WJEC videos...😔 My thanks to the uploader.

Earned yourself a sub :) One question though... Can ionization only occur when losing electrons, or could it also happen when gaining electrons? But thanks alot, also i like your accent!

Thank you so much

Hi, sir! You're defo a godsend! My Edexcel IAS exam is 3 weeks away and I'm under-prepared, so watching your videos in the last minute to get away with Chemistry for AS. My question is, your videos do cover Edexcel IAL syllabus entirely, don't they?

Where have you been my whole life

You my friend are very helpful

Hey e rintoul I was just wondering, if I use just your videos ignoring all other sources of info e.g. Textbook Will it be enough for me to secure top grades?? As I believe your videos cover the entire spec really well

thank you sir

You are a hero

In a level papers the periodic table will be given or do we have to learn the relative atomic mass of each element?
