DOES THAT MAKE ANY SENSE TO YOU?
IF NOT PLEASE CALL 1-800-NED-CHEM THERE YOU WILL GET ALL.
okay time to get REAL serious.
So what does this electron configuration mean? its basically how each electron is place in an atom.So there are 2 numbers one is energy Level and the other is number of electrons in that energy level and orbital
Energy level is the number in the front "n" and the energy difference between 2 energy levels is called quantum of energy. COOOL quantum... = =.
now there is this thing called ground state and excited state.
ground mean its stable and will most likely not do some random explosion.
excited means its excited... imagine an excited person.. what will he/her? yea jump around and that is what the electron does too... it jumps.. to the lower shell to gain stability and become ground. In this process it releases energy..SO MUCH TALKING BORING...
Orbital = region of space used by an electron in an energy level s.p.d.f
Shell = a group that have the same orbital and n value the 1.2.3.4.5.6.7 # in the front
Subshell = the s p d f thing that are in the same shell like 1s 1p 1d 1f but they contain different numbers of electron
in n=1 shell there can only be s type
n=2 is s and p type
n=3 is s p d type
n=4 s p d f type
all s type subshell can have 1 s orbital
p have 3 p orbitals
d have 5 d orbitals
f have 7 f orbitals
and each orbital can have 2 electrons...
IN CONCLUSION
s subshell can have 2 electron
p have 6
d have 10
f have 14
Higher "n" number = less stability.. and = more energy release when it get excited and jump that's why the uuu stuff can only live for a millisecond
this is boring right?
i agree...
the order is 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p
7s 5f 6d 7p... BUT THAT IS LIKE NERD LEVEL MEMORIZATION
so normal people like me who isn't no-life science person use the
awesome graph of love
and yes this is as easy as it gets.
Electron always fill from the lowest.. so THERE WILL ALWAYS BE 1 + electron in 1s if u don't have 1s something is wrong...
Also electrons likes to be by themselves instead of pairs... so ALWAYS ^ ^ ^ and then v v v (yes i know they are v's... to bad)
negative Ion just means its full shell it will be like the next noble gas easy yes
positive ion isn't so cool... if its +5 you have to take away 5 electrons and if there are electron in s and p orbitals p is removed first (plz don't ask why only some random chem nerd will be able to answer you that)
by this point you are probably wondering why I'm not finish yet... (yea i know life suck i got a long blog live and read plz, apparently we learned a lot today so too bad...)
Okay now Core notation
Core Notation = above row NOBLE GAS + Valance electron config and yes this makes your life easier... BUT the teacher can be mean and make you write Uranium and make you write in stander form lovely isn't it?
WE ARE ALMOST DONE
now we got 2 bad boys Cr and Cu they are bad because THEY START WITH C don't confuse with Cs which stands for counter strike or Cd... or Dy just because people aren't that smart these days
All ions and noble gas have full valence shells the + - sign on the atom means - means its needs w/e amount of electron
+ mean it needs to get rid of w/e amount of electrons
example Ag [Kr] 4d10 5s1 and Ag ion will be [Kr] 4d10
also there is this open and close shell thing...
open = not full still open...
close = to bad no more electron is accepted and is close for business.. = full shell...
Examples
U uranium?? electron config??? STANDER FORM YES I AM MEAN
okay i give u answer... just incase your teacher give u this...
1s2,2s2 2p6,3s2 3p6 3d10, 4s2 4p6 4d10, 5s2,5p6 5d10 5f3, 6s2 6p6 6d1, 7s2
this is torture mode
normal mode.. [Rn] 5f3 6d1 7s²... OMG SO MUCH SHORTER
okay Ga is next
1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p1
core is [Ar] 4s2 3d10 4p1
yea now its ion is since its +3 so you have to get rid of 3 electron and always start from p then to s so answer
[Ar] 3d10 too bad no stander form its happy so yay and stable..
like electron config can't really have really weird questions so just pick random element from periodic table and write the electron config.. REMEMBER CR CU!!! THEY = EVIL
always end with youtube yes
