Questions and Answers
Why is the electronic configuration of Pd an exception among the elements mentioned?
Why is the electronic configuration of Pd an exception among the elements mentioned?
- Because it has 4s orbital completely filled
- Due to the stability of having ns orbital with 0 electrons
- Due to the presence of 4d orbital in its outermost shell
- Because of the small energy gap between 4d and 5s orbitals (correct)
What is the reason behind the electronic configuration of Cr being 3d5 4s1 instead of 3d4 4s2?
What is the reason behind the electronic configuration of Cr being 3d5 4s1 instead of 3d4 4s2?
- Prevention of electron entering the 3d orbitals due to a small energy gap (correct)
- Large energy difference between 3d and 4s orbitals
- Presence of completely filled orbitals in the 4s orbital
- Stability of having half-filled 3d orbitals
Why does the electronic configuration of Cu differ from what would be expected based on the general rule?
Why does the electronic configuration of Cu differ from what would be expected based on the general rule?
- Significant energy difference between ns and (n-1)d orbitals
