OCR A 2.2.1 Electron Structure REVISION

[@m_ahmad7006]

That bus analogy was so accurate, some people would rather stand than sit next to someone else😂

[@anakinskywalker3777]

I'm an electron, i dont wanna be near anyone haha, thank you so much for the great video and amazing helpful explanation.

[@AlleryChemistry]

Glad you enjoyed it!

[@farhaanahmed8924]

Can't thank you enough, am recommending these videos to my classmates and friends!

[@AlleryChemistry]

Please do! Thanks very much!👍

[@MrExtremeGamer2]

Thanks these videos are very useful. I would recommend! After doing a couple of notes I would watch your videos and it would just secure the topic for me!Thanks

[@nizaibrahim9340]

We need you to teach at Middlesbrough college please 😭

[@AlleryChemistry]

Heh. Someone else asked that today ha! Must be a few leaving then! I don't live far from there (Morpeth)

[@shafinbepary2000]

it's funny how our teachers use these slides haha ! whoever made is a legend they are so spec specific !

[@AlleryChemistry]

Thanks. I made the slides, I'm pleased they are helping to make chemistry that little bit easier to understand. 👍

For iron's electron configuration, isn't it wrong to write 3d^6 after 4s^2 ???

[@lubandlovu00]

You are an angel

[@shyamkanjee6409]

please, can you tell me the difference between an orbital and a sub-shell I can't wrap my head around it.

[@mtsl7780]

an orbital is a region around the nucleus that can hold up too 2 electrons with opposite spins.

[@yujirohanma203]

@@mtsl7780 wrong, an orbital is what we call electron level or shell, and subshells are what hold 2 electrons with opposite spins

[@sophiereading7629]

If an element had all electron shells filled up to one electron in 3d and it then lost an electron, would the electron be lost from the 3d orbital first which 'technically' has a higher energy level, or would it be lost from the 4s orbital?? and why :)

[@salinahenley5635]

very helpful video thank u !!

[@daniatbz]

hello can you please come teach at Middlesbrough college all our teachers are leaving please

[@AlleryChemistry]

Ha. Not far from where I live actually (Northumberland).

[@daniatbz]

Allery Chemistry you should definitely consider it

[@AlleryChemistry]

Heh. Used to teach in Ashington but don't teach in schools now. Suppose I am one of the many vacating the profession. Teaching of chemistry, physics and maths is in a recruitment crisis so those teachers are in high demand. Shame really, education is so important.

[@daniatbz]

Allery Chemistry I know! thankyou so much for your videos, they're soooo useful.

[@AlleryChemistry]

You're welcome! Hope your course goes well with whoever teachers you get.

[@raheemtahir427]

what a legend come to wilmington Grammar

[@DiamonDanielVlogs]

Can u make edexcel revision vids pls

[@AlleryChemistry]

These should appear by start of next week.

[@DiamonDanielVlogs]

thank you soon as possible please because ur vids are great

[@nicolegourin2417]

Hello, when are the module 3 & 4 videos going to be out? Thank you :)

[@AlleryChemistry]

More uploaded tonight.

[@nicolegourin2417]

Thanks, really appreciate it. These are a life saver!!

[@AlleryChemistry]

No problem

[@koysherchaudhury8010]

Hello. When will the A2 videos for ocr like this be out?

[@shyamkanjee6409]

Hi, sir can you explain whats the difference between what orbitals are and what subshells are to me, I'm still a bit confused in their definitions.

[@roxers8700]

the subshell is a group of orbitals of the same type within a shell whereas an orbital is where the electron is more or less likely to be found.

[@killer-for-hire9643]

Are these specs the same as the 2019 spec or do i have to learn more

[@shyamkanjee6409]

The axis that you've labeled at 4:21 are wrong for the two of the p orbitals

[@iqpro7701]

I checked by CGP book and it is correct

[@mustafaali8287]

at 7:58 isnt it supposed to be 3d10???

[@iqpro7701]

If you go the d-block in the periodic table you will see that Fe has 6 electrons in the 3d sub-shell. Another way to explain it is by remembering that the 4s sub-shell has lower energy so it fills first resulting to it having to be in the configuration. I got all that from the CGP book btw
