5 Questions
Why is the electronic configuration of Pd an exception among the elements mentioned?
Because of the small energy gap between 4d and 5s orbitals
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
Why does the electronic configuration of Cu differ from what would be expected based on the general rule?
High stability due to the presence of a half-filled 3d orbital
What property makes half and completely filled sets of orbitals relatively more stable?
Low energy gap between different sets of orbitals
In the general electronic configurations of these elements, what does 'n-1' represent?
Number of electrons in the inner d orbitals
Learn about the general electronic configuration of elements where the outer orbitals are (n-1)d 1–10 ns 1–2, with exceptions like Pd having an electronic configuration of 4d 10 5s 0. Explore the exceptions caused by minimal energy difference between (n-1)d and ns orbitals, as well as the significance of half and completely filled sets of orbitals.
