Which is more stable :half filled d orbital or fully filled d orbital?

Posted by Sourav Sharma 7 years, 7 months ago

CBSE > Class 11 > Chemistry

4 answers

Shreya Singh 7 years, 7 months ago

Fully filled d orbital I think,coz orbitals which r half filled do certainly have unpaired electron or electrons with all the spins oriented in one direction.So certainly they r unstable.Orbitals which r fully filled have all the electrons paired.Hence they r highly stable.

Ďãřşháñăã Yadav???✊ 7 years, 7 months ago

I think Google have right answer of it...

Aman Kumar 7 years, 7 months ago

I think fully filled d orbital bcoz each subshell can contain only 2 electron with opposite spin.so , it will be more stable , i think.

Ďãřşháñăã Yadav???✊ 7 years, 7 months ago

I think... Half-filled orbitals are quite stable because of the electrons' spins being aligned; they resonate and so are stabilised.

1 answers

Sia ? 4 years, 7 months ago

Molecular Mass	Gram Molecular Mass
It is a number equal to the sum of the atomic masses of all the atoms in a molecule. It is relative to the 12C, which has a mass of 12.	It is the mass in grams of 1 mole of a molecular substance.
Example: H₂O has molecular mass 2+16=18	Example: The molecular mass of N₂ is 28 so gram molecular mass of N₂ is 28.
