What is an invalid orbital designation 4p 3s 2d 5f?
The orbital designation "4p 3s 2d 5f" is invalid because it does not follow the proper order of filling orbitals according to the Aufbau principle. The correct order is 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, and 7p.
What are the expressions for the Fermi wave vector in 1D 2D and 3D?
The Fermi wave vector expressions in 1D, 2D, and 3D are given by: 1D: k_F = (3π^2n)^(1/3) 2D: k_F = (πn)^(1/2) 3D: k_F = (3π^2n)^(1/3)
Why do electrons enter the 4s orbital before entering the 3d orbital?
because its energy level is lower
Is that 4s or 3d orbital to which an excited electron from 3p would first go?
An excited electron from the 3p orbital would most likely jump to the 4s orbital due to its lower energy level compared to the 3d orbital.
Why 4S orbital is filled before 3d orbital during writing electronic configuration Explain with the help of n l rule?
The filling order is determined by the Aufbau principle, which states that orbitals are filled in order of increasing energy. In the case of chromium, the 4s orbital is actually higher in energy than the 3d orbital due to electron-electron repulsions. This means that the 4s orbital is filled before the 3d orbital according to the n + l rule, which states that orbitals with lower values of n + l are filled first.
