If Giant Covalent Structures are only made of atoms then Silicon Dioxide is an molecule?

as a visual learner, your videos are more effective than my teachers' explanation

[@_Xypes_]

as someone who just wants concise explanations, questions and to be told what to do, this channel could've got me through gcses without teachers in 2 weeks. absolute mf godsend. never studied before a couple days ago and now i'm almost certain i'm gonna get a 9 in every subject bar music and eng lang in my mocks, and i've still got plenty of time to fix those before actual exams

Just hats off......... This channel went to the extra mile by not only uploading convenient science videos but also the explaining, the voice, the figures are so easy to watch like the only thing you need to do is to listen once or thrice and boom you get to know what you're looking for. Thanks Cognito💙

Simple covalent molecules MOSTLY do not conduct electricity. Aqueous solutions of acids and ammonia, however, do conduct electricity.

Question: Are covalent bond intramolecular forces?

[@deathfighter818]

doesnt graphite have imf between the layers? and if so does that not affect the bp and mp?

[@vlvt-things]

clear and concise explanations, thank you

[@Cy_unreal]

Watching this day bf the test😅

[@daniella7115]

How come the melting & boiling points of single molecular substances are dependent on the intermolecular forces not bonds, but the melting & boiling points of giant covalent structures are dependent on the covalent bonds as opposed to intermolecular forces?

How to know if a substance is a simple or giant covalent molecule based on its structural formula?

[@Cognitoedu]

Hi, you can sort of figure it out, but it's quite complicated. It's best to just memorise the few examples of giant covalent structures.

[@telepathyavos3786]

This video is quite confusing. It first says that the bonds between the atoms do not break, instead, the intermolecular forces break. This was said in the part about simple covalent structures. However, for the giant covalent structures, he states that the covalent bonds will have to be broken, instead of the intermolecular forces.

[@Cognitoedu]

Hi there - yeah that is the main confusing point in this topic. For simple molecular substances it's the intermolecular forces (weak forces between the molecules) that need to break to melt the substance. Whereas for giant covalent structures (like diamond), it's the strong covalent bonds that have to be broken.

[@sadiafareed7151]

Your videos help a lot

[@jonb1465]

Why are there more intermolecular forces between bigger molecules???????????

[@UZU919]

There are more molecules on giant covalent structures so realistically more intermolecular forces to overcome

[@thebismillahkitchen6082]

Are there any more videos coming up??

[@Cognitoedu]

Yes there are! Stay tuned!!

What is exactly meant by free electrons? I never understood that part.

[@UZU919]

The electrons are not on the outer shell of the atom so are free to move about
