@Ϻ.Λ.Ʀ. Sorry, @Loong, but your URGENT is in a different castle title.

@Ϻ.Λ.Ʀ. Nice, you are now tetrakis <3

Oooh, apparantly @Ϻ.Λ.Ʀ. is not here, so I can get pinging revenge =D

But I have to be careful about pinging @Ϻ.Λ.Ʀ. or some mod™ might ban me D=

But I'm sure @Ϻ.Λ.Ʀ. will have mercy upon me =D

!

How many cross-couplings have you catalysed since turning into tetrakis, @Ϻ.Λ.Ʀ.?

Hi @Loong o/

@Jan Hej

Oooh, are we turning Swedish? =O

Nah, it's Polish :)

Hm, I first think of Swedish when reading hej (and Finnish when reading hei) ^^'

@Jan Dunno but in Polish hej=hey

@tschoppi o/

heyo

Anyway @Ϻ.Λ.Ʀ. I hope you'll enjoy my pings tomorrow.

Don't forget to check out/criticise my new posts @Ϻ.Λ.Ʀ.!

And with that, I say good night to @ina, @Ϻ.Λ.Ʀ., @Loong, @Mith and @tschoppi (and I can't help but wonder why us central Europeans are still here even though it was two a.m. ^^')

Probably @Ϻ.Λ.Ʀ. has a proposed solution xD

@Jan good night

@Jan g'night

@Jan good night!

@Ϻ.Λ.Ʀ. Nah. Just venturing around, being busy a bit.

@Jan I'm gonna catalyze you now! ლ(ಠ益ಠლ)

@Jan I can't count

@Ϻ.Λ.Ʀ. hey man! finally I am chatting to you live!

@Ϻ.Λ.Ʀ. 18/20 isn't that bad...

what were to two questions you missed?

And for once, I'm [pretending] not to be busy.

how did the other exams go?

@TanMath I'm just bored. I don't wanna talk about it.

@Ϻ.Λ.Ʀ. is that a hint that you do not want to talk to me?

The other ones went better.

@Ϻ.Λ.Ʀ. ok...

@TanMath Nah, it's a hint that I wanna find someone to chat with.

@Ϻ.Λ.Ʀ. nice. 18/20 isn't that bad! it is still an A... if it is something you do not want to talk about, I will end it here.

I should think of a good time to ping-attack @Jan.

@Ϻ.Λ.Ʀ. good!

@Ϻ.Λ.Ʀ. now?

Like, when @Jan's not expecting it.

Not right now. @Jan would expect that.

@Jan is smart. Cough

that makes sense.

＼（＾▽＾）／

It makes sense to @Jan too.

hey @Mart!

^ does that ping?

@Martin-マーチン \o

@TanMath Yeah

@Jan say hello to Mart.

lol

heyooo/

@Martin-マーチン . . . per message

ಠ_ಠ

ಠ_ಠ

@Jan ಠ_ಠ

@Ϻ.Λ.Ʀ. she is going to get creeped out and angry.

@Jan why don't you say "hello" to Mart? ಠ_ಠ

@Ϻ.Λ.Ʀ. from my friends @ PPCG

@Jan you should say hello to Mart RIGHT NOW!

they know how to creep...

@Ϻ.Λ.Ʀ. she lives in germany?

@TanMath More precisely, the underworld

I think he is still asleep

ok. makes sense. They would need chemists down there...

@Martin-マーチン I thought @Jan was a she...

problems of internet chat: 1. getting gender wrong

@Martin-マーチン @Jan is not a he.

@Jan is referred to as an it, just like any other molecule.

Right @Jan?

Are these many pings enough @Jan?

Or should I ping more @Jan?

wait, what?

@Jan confirm what @Ϻ.Λ.Ʀ. is saying right now!

@Martin-マーチン is your mind=blown?

^ another PPCG thing

Should I ping you more @Jan?

That's another PPCG thing @Jan.

Thought you should know @Jan.

rofl...

Enough for now @Jan.

this is too funny...

Hope you learned your lesson @Jan.

Well... well... well...

@Jan come here now before I die on the floor laughing

I guess someone else needs a lesson here

@Jan don't make me dotfl

@Martin-マーチン Hello mister mod O:)

me runs

@Martin-マーチン Yeah, I should study some NMR.

@Jan knows a lot of NMR.

@Jan knows a lot about OChem in general...

maybe when I have OChem questions, I should ask @Jan!

Well, that's like, 30 pings. Way to go team.

I feel like we finished a TRE or something...

you know, we three would make a good TRE team...

just saying...

haha... if only i had time

then what are you doing here?

you must have time to chat with @Ϻ.Λ.Ʀ. at this moment, right @Jan?

there was a ping and I am waiting for @pH13 to come online, because I have questions

@Ϻ.Λ.Ʀ. why were we bothering Jan?

just to fulfill revenge?

No, it was for SCIENCE.

makes sense.

@Martin-マーチン Mods can superping; who can supersummon?

ok...I better go to sleep right this instant! goodbye!

@Ϻ.Λ.Ʀ. what do you mean with supersummon?

@TanMath Goodbye this instant

@TanMath nighty-night... sleep tight, don't let the bedbugs bite

O_o

That's @Jan's evil twin.

Or @Jan is her evil twin.

stop it now, seriously... I am sure it will be annoying enough

@Martin-マーチン I don't mean to continue ping attacking January.

ah

@Martin-マーチン What element is that?

Ahhium?

it could be if you find it

@Ϻ.Λ.Ʀ. Hello to @Mart o/

Hi @Jan

Haha, 37 pings, well done =D @ina @Ϻ.Λ.Ʀ.

Hi @Simon o/

Hi yo/

Hi @Martin-マーチン

Also I wasn't asleep. It was past 12 p.m. already. I was having Lunch xD

OMG lunch... how could you...

@Jan Well i have finished dinner

@Martin-マーチン I only ate sweets and had a cup of tea ;)

@Jan Ireally interesting combination

@Jan Bows

@Ϻ.Λ.Ʀ. *pats you on the shoulder*

Who's you?

Uranium?

But I'm tetrakis.

You as in second person pronoun; common English usage.

I know.

Always helps to look at stuff the punny way.

I should have written yousage

@Cop's here.

Hey @Cop

Good evening, Muhammad! I only peeked in to ask about CuSO4, but then I found some info on the web.

@CopperKettle That compound . . .

So, what was your question?

I'm trying to understand how it is put together. There seems to be too many electrons on S. There's the Wiki page that seems to explain it.

> The first description of the bonding in modern terms was by Gilbert Lewis in his groundbreaking paper of 1916

I'll read it now.. (0:

BBL!

@CopperKettle So it's sulfate you're worrying about.

And what about bonding do you want to understand @Copper?

You see, we have a problem.

Things like bonding, we never "understand", in the literal sense.

It's just way too complicated.

Instead, we make models and understand those that fit experiment.

So we're not understanding reality; we're just trying to understand the closest and simplest stimulation of reality as we can.

So be it balls and sticks, or big bad-ass equations, we're understand a scientist's perception of reality @Cop.

So, what model are you trying to understand @Cop?

If it's drawing the Lewis structure of the sulfate ion, just draw an S with its valence electrons, add the number of electrons the charge tells you (in the case of sulfate, it's 2 extra electrons), and then draw beautiful bonds. In the case of sulfate, 4 dative bonds to oxygen atoms.

If it's MO, then excuse my lack of drawing ability in chat.

If it's hybridization, it's sp3.

Roughly.

I think.

I learned that in SO2 we have sp2-hybridization, but there's seemingly nowhere to promote one of the S2 electrons in S, since all the 3 of its P-slots are occupied. Probably one of the oxygens draws one electron towards itself, and this allows hybridization to happen, like here

I'll read about it tomorrow. (0:

Good night!

@CopperKettle Yes, because that’s not how it works. That you do it that way in high school is just to 'explain the way' to four equivalent orbitals pointing in the tetrahedral direction. But actually it is much more appropriate to say that electrons just find the orbital that has lowest energy, and then it's us silly humans sitting at the sideline and thinking:

> Now how can we explain that in hybridisation methodology?

But if you really want to do it that way: In sp², you have a spare p-orbital; promote the electron into that.

Does someone want to give me one single upvote within the next hour? Pretty please? =*,…,*=

Thank you, nice people <3
