Periodicity - trends

A real trend setter! This video will look at how electronegativity, first ionisation energy and atomic radius changes across periods. Includes those sneaky deviations in ionisation energy trends.

Thx!!! I'm having an Alevel today and I think I am well prepared learning with you!!!

[@shahzahantapan3279]

How was your results?

[@fredlabina9179]

ur the best mr allen.You make it so simple to understand the concept

[@sarahsandy2204]

wow! thank you so much - this is needed!!

[@mobap1554]

Thanks for the vids! Have you got one on Diamond, Graphite and Graphene's structures, bonding and properties for AS? Just had a quick check through the playlists and I couldn't seem to find one.

[@AlleryChemistry]

No problem. Here is the vid that may help you - th-cam.com/video/-FPnLu7GVF0/w-d-xo.html

your video is amazing, you explained it all so well and in good time as well! this really helped me!

[@AlleryChemistry]

Glad it helped!

Can u Make a play list for cie students alevel chemistry

[@Ojay9]

Good man!

thank you my friend.

I dont quite understand if electron repulsion between electron pairs in a 2p orbital makes removal easier,why does the same not hold true for paired orbitals in the 2s orbital?

[@ace1879]

The attraction to the nucleus (since they're much closer to the nucleus than 2p orbitals) overcomes the repulsion between the electron pairs.

Great Vid!

[@AlleryChemistry]

Thanks very much! Pleased it helped you.

[@taskeennadramughal4916]

Plz make a video on nmr peaks

[@louiebradley5900]

Thank you so much

[@AlleryChemistry]

You're most welcome

[@shakermohammed4260]

Why flourine has higher energy than oxygen, even though we are increasing the repulsion

[@killer11843]

Hi are all your videos relevant today ?

[@AlleryChemistry]

Yes. All for new spec

[@killer11843]

Thank you very much
