26:24 So would you say the reason why P, S and Cl have slightly higher mps than argon is due to the covalent bonds being present which need energy to be broken aswell as vdw forces too, while argon only and only has vdw forces to break?

@chemistrytutor

9 ай бұрын

No, I'm afraid that's not it. When you melt something you don't break any Covalent bonds. Think about ice... its solid H2O, water is liquid H2O. All the bonds are still intact. It's due to the Molecules that you mentioned being larger than an argon atom there is additional surface area so the vdw forces between Molecules are stronger. Stronger (or more) vdw forces means that more energy needs to be put in to break them

@@justsomeone5660 well, I've already made some videos about these topics. They're exam question focused, so whilst I don't go through all the facts one at a time, they deliberately cover a lot of the content drive.google.com/file/d/1s3I5prjbJRR1U1lcKpXO9TQpQMaVoP66/view?usp=drivesdk

so electronegativity decreases down a group because there’s more energy levels -> causing a wider distance between outer electrons and nucleus -> therefore less pull from the nucleus. but if the effective nuclear charge stays the same down a group, how can the nucleus have less pull? is effective nuclear charge and the nuclear charge mentioned in the video different?

@chemistrytutor

7 ай бұрын

It's that nuclear charge (which does increase as you said) becomes less significant than the increase in distance down the group along with the extra shielding. The decrease in attraction caused by these two things is much more significant

Grt explanation!

Hi, yes I have... here you go kzread.info/dash/bejne/gWuXxdWBfsvJmJc.html

why dont you talk about how shielding affects ionisation energy and and electronegativity? These are valid points aswell.

@chemistrytutor

3 ай бұрын

You're correct, shielding can definitely affect those properties. However, when considering the pattern across a period (which is what periodicity looks at) the elements in a particular period all have the same shielding, so that wouldn't explain any changes you observe. If we'd been looking at a pattern down a group you would be correct to mention an increase in shielding

thanks, why is there not a dip on Mg where 2 electrons are in 1 orbital in s subshell 15:53

@chemistrytutor

Жыл бұрын

Great question. I think there is, slightly, but its masked by the s orbital being closer to the nucleus than p. So the repulsion is outweighed by being closer to the nucleus that has a higher nuclear charge

@chemistrytutor

9 ай бұрын

You've asked a really simple sounding question that actually has a number of very complicated answers. You don't need to know if for a level but the explanation that ties in with something you do need is that its to do with shielding (some places call it screening) and electron-electron interactions. The deeper you go into electron orbitals the more our model gets refined by quantum mechanics. So if you want to go further, that's the direction to go.
