Any reason one can give me to help me understand why when orbitals have all filled the energy of the system decrease (more stability)?
So the octet rule says that an atom is stable when it has 8 valence electrons which I understand because 2 + 6 = 8 as Xs2 and Xp6 is 8 all together. What I don't understand however is how this works for D and F block elements because if an atoms outer energy level is 10 or 14 then surely it would accept more than 8 electrons
Similarly why cans sf6 exist? sulfurs valence energy level is 3p6 so how can it accept more than 2 electrons . online textbooks say that it is possible to excite electrons into 3d but how is this possible when 4s2 must be filled first?
Apologies if these questions seem stupid I have not being taught about d/f block elements
Hello, I've noticed an iOS device on my WLAN is querying lb._dns-sd._udp.0.7.168.192.in-addr.arpa a LOT.
Any ideas?
I am a high school student,so I want a high school student level explanation Its been like 2 days trying to find the answer Any help is appreciated
Oh fish he ate, officiate oafish-y eight.

I was inspired to compose a piece based off of themes from J.S. Bach's Organ Trio No. 1 in Eb Major, BWV 525. When I first began this work back in July, I decided to write it for and according to the preferences and skills of the performers that I had available and willing. In doing so, I hoped that I would actually get it played live (you'll notice that most of the music on my channel is still generated from Finale). Well, unfortunately, due to some ensuing drama and severing of ties and friendships, as well as a few other outlying circumstances, that fell through, but I wanted to finish what I started. Here's the score in its entirety, with audio generated by NotePerformer 3.3.2. If anybody is interested in trying the piece out for themselves, or would like for me to arrange it for an alternative ensemble, feel free to shoot me an email at trevormcintosh110@gmail.com. I should also have free .pdf's of the score and parts uploaded to my website here pretty soon, at trevortmcintosh.com.
I. Allegro moderato - a mostly joyous movement in Eb Major, organized in a kind of rondo form
II. Adagio 5:21 - a slow and intensely somber A section in C Minor is followed by a more content (if somewhat austere and proud) B section in G Phrygian. The movement is then capped off with a fugal section that combines both themes in C Minor
III. Allegro 20:22 - a celebratory, almost fanfare like section in Eb major is followed by a tense, almost wailing B section in F Dorian. The entire octet is then capped off with a fugue that recalls all of the themes from each movement.
Happy listening! :)
Shouldn’t a negative change indicate the presence of extra electrons? I know that it is Cl- but why isn’t it Cl+ since it is so electronegative why doesn’t it have a positive charge in its ion form?
Hey all!
I'm writing some material for a jazz octet album (trumpet, alto sax, tenor sax, trombone, bari sax, guitar, bass, drums) and I was wondering if anyone had any recommendations for jazz octet albums I could check out?
I just wanna get a sense for how the jazz octet has been used in the past (and also how it's being used now) so that I have a foundation I can build upon. The albums don't need to have the exact line-up that I'm using, just as long as they have at least four horns I'm happy.
So far I've been checking out the Dave Pell Octet, Oliver Nelson on Blues and the Abstract Truth, and Kenny Wheeler's Music for Large and Small Ensembles.
Any recommendations would be greatly appreciated :D
I’m trying to build an electron app to upload some files by chunks in a remote server, I have an express instance that is receiving everything ok but the body is an empty object
As the title stated.
What are the rules/procedure when drawing central atoms with P orbitals? Is the maximum number of orbitals for the central atom always 6? If not, how do I determine the maximum number of orbitals for the central atom?
ex:
ClF5 (note: Cl means Chlorine)
SeCl6
SF3Cl3
I understand that for compound that follows the octet rule: you draw the lewis structure by 1. determining the total number of e- by adding up the valence e- from each atom 2. distribute the e- in a way that fulfills the octet rule.
Please let me know if my question wasn't clear to understand.
Any advice is appreciated. Thank you very much!
