The exactly half-filled and fully filled orbitals have greater stability than other configurations.
The reason for their stability are symmetry and exchange energy.
(a). Symmetry
The half-filled and fully-filled orbitals are more symmetrical than any other configuration and symmetry leads to greater stability.
(b). Exchange Energy
The electrons present in the different orbitals of the same sub-shell can exchange their positions. Each such exchange leads to the decrease in energy known as Exchange Energy. Greater the number of exchanges, greater the exchange energy and hence greater the stability. As the number of exchanges that take place in the half-filled and fully-filled orbitals is maximum, thus exchange energy is maximum and hence maximum stability.
Nice
ReplyDeletenot satisfactory man chemwiki
ReplyDeleteI did not get my answer. Please explain in detail
ReplyDeletethanx
ReplyDeleteWhich is more stable? Half or completely filled?
ReplyDeletecompletely filled.
DeleteFully filled
DeleteFully filled
DeleteBoth half filled and full filled is symetrical
DeleteFully
DeleteWhich is more stable? Half or completely filled?
ReplyDeleteDidn't understand properly, elaborate more please
ReplyDeleteDidn't understand properly, elaborate more please
ReplyDeleteitz good and well explained if someone can't understand just go to the basics
ReplyDeletewhen the subshell is half filled electron is arranged in symmetrical manner such that the net force due to nucleus and other electrons becomes low and the stability of electron in an atom increases.
ReplyDeletealso due to possible exchange in position of electron the stability increases.
suppose you have 3 house and i have one. if both of us will have to leave one house, u still has 2 houses so u can go there. but what about me, i will become unstable. i guess now u can understand. :)
Can u elaborate it nicely
ReplyDeleteThank you so much. So well explained then other rubbish answers
ReplyDeleteWhy is number of exchanges greater in half filled or full filled orbitals
ReplyDeletebecause of same spin
Deletewhen they exchange there position in degenarate orbitals there should be no loss of energy as energy all same for all . Please tell why this happen ?
ReplyDeleteA fully filled 3d and partially filled 3d which on will have the greatest stability

ReplyDeleteThanx for this knowledge it really helped me a lot please reply
ReplyDeleteYou're welcome
Deletenice explain.
ReplyDeleteThe answer wasn't clear enough. 😢😢
