How do you work out when to say what forces and bonds are being used and how to work out if something is giant covalent/ionic or simple molecular etc... I understand them all individually but I’m struggling to work out when to apply what

[gelato]

Do your videos cover all of OCR A spec or is it just a few videos

[shumailaiftikhar]

This might be a silly question but how can you tell that silicon has a giant covalent structure?

Isn’t shielding basically the same as atomic size?

[p.p]

Hi, why does atomic radius decrease across a period? The number of sub shells increases across a period so wouldn't this cause the radius to increase? Thanks

HI
I know it has been a whole year since the video was uploaded but got question
u say simple molecular bonds does not conduct electricity
but how come water is an example of simple molecular bonds and can conduct electricity

How do the delocalised electrons in graphene strenghthen the covalent bonds between the carbon atoms?

When are you going to make the ocr A2 videos?

Hi!
What's the difference between nuclear charge and effective nuclear charge, does it matter if I just use nuclear charge in the exam?
