Help me with chemistry

[orangecat]

So i'm taking a chemistry class and i cant get my mind around electron configurations and sub energy levels. I know it has something to do with 1s2 and 2p6 but i don't know what all this means so if you guys know anything about this kind of stuff or know of some nice resources i can look at that would be great.

That is physX.

[tryphaa]

That is phyXs. 

nvidia pls

[antoainb]

That is phyXs. 

 

Sorry OP for off topic but it's PhysX, not phyXs.

Two electrons occupy each of those lines, (starting from 1) and they fill up the lines like a bus of antisocial people would fill up, you don't want to occupy a seat next to another person.

so carbon which has 6 electrons would fill up 2s1 2s2 2p2 as shown below   (I'm probably wrong, can't remember this stuff.)

 

a great resource for quickly figuring this stuff out is the Aufbau table.  If you understand that then understanding electron configurations becomes easier.

It's been forever since I learned this stuff so naturally I don't remember any of it and haven't used it since Second year.

You are being very picky.

Thanks for trying to help but it didn't really do much.

those diagrams make it seem way harder than it really is.

Really? I find them very intuititive. The higher the energy level of the level the later it becomes filled with electrons, so all you need is a little trick like that Aufbau table to make sure you remember the order and it's just a matter of filling them in.

im not the one who needs help, i have learned it another way i guess.

That is a interesting way to put Hund's rule.

However it leaves out the part where orbitals of the same energy level will only be occupied by electrons with parallel spins.

In short it is not possible for the orbitals 2p^x and 2p^y to be occupied by a electron of the spin -1/2 and 1/2 on the other one. Both have to be either -1/2 or 1/2.

Also I never really noticed how much German words there is in chemistry, I always only learned it in German.

What exactly is it that you are trying to understand?

1s² is the electron configuration of Helium.

2p⁶ is the electron configuration of the outermost electrons of Neon.

And this just reminded me that I have a chemistry test to study for tomorrow...
