in NICKEL element!!!!
UnkleRhaukus
  • UnkleRhaukus
start at the top left of the table , for example element 26 Vanadium \[1s^22s^22p^63s^23p^64s^23d^3\]

hey!!! it comes in 10 class!!!!

i need diagram of element NICKEL elect. configuration
mayankdevnani
  • mayankdevnani
@UnkleRhaukus what is the elct.configuration of nickel element with the help of diagram!!!! can you plz help me!!!
UnkleRhaukus
  • UnkleRhaukus
well the noble gasses has stable configurations so you can used the next lowest noble gas as your base,
UnkleRhaukus
  • UnkleRhaukus
then fill out the next few shells with an electron for each extra position on the table |dw:1355408553013:dw|
UnkleRhaukus
  • UnkleRhaukus
according to the table how many electrons are in the 3d orbital for nickel?
mayankdevnani
  • mayankdevnani
hey!!! thnx for guiding me!!!! but in the M shell of nickel there are maximum no. of 18 electrons but in elect. conf. chart it is given that in M shell it has 17 electrons!!! that's was my problem!!!!
mayankdevnani
  • mayankdevnani
i even don't understand!!! it is a high level!!!

wait my diagram is a bit inside out ,

UnkleRhaukus
  • UnkleRhaukus
im not sure where you got 17 from?
UnkleRhaukus
  • UnkleRhaukus
i think ive been confusing you, ive been talking about electron orbitals, and youve been talking about electron shells
UnkleRhaukus
  • UnkleRhaukus
have a look at this page http://upload.wikimedia.org/wikipedia/commons/a/a8/Periodic_Table_of_Elements_showing_Electron_Shells.svg

hey!!! m in 9 class and i don't know that what is orbitals?? i only knew elect. configr. see comment of Makalya scroll-up and see nickel element el.con.

@hartnn plz help!!!

@UnkleRhaukus plzzzz don't go

i dont know if i can explain this, my head is full of orbitals , and shells are confusing me

not orbitals!!!!!!! by elect. config.
ghazi
  • ghazi
just remember a fully filled d orbital or half filled d orbital in this case makes it more stable

and that of nickel?
mayankdevnani
  • mayankdevnani
DLS
  • DLS
2,8,16,2
mayankdevnani
  • mayankdevnani
but in Makalya 's comment
mayankdevnani
  • mayankdevnani
it is different
DLS
  • DLS
forget that comment
mayankdevnani
  • mayankdevnani
okk
mayankdevnani
  • mayankdevnani
but in M shell it has 18 max. electrons
DLS
  • DLS
dont ask why it did not fill up 18 first,that is beyond ur scope if ur in 9th,ull learn about it in class 11 when u learn about orbitals and shells.
DLS
  • DLS
take it as an exception and move on
mayankdevnani
  • mayankdevnani
in Chromium!!
DLS
  • DLS
thats an exception too
mayankdevnani
  • mayankdevnani
ohkkkk
ghazi
  • ghazi
chromium has an exception
DLS
  • DLS
u will read why that happens in "Afbau Principle"
mayankdevnani
  • mayankdevnani
okkk
DLS
  • DLS
half filled>>>full filled
DLS
  • DLS
u dont need to know anything more,wait for some time and dont think too much
