Where, ℓ = azimuthal quantum number of the subshellįor s subshell, ℓ = 0 For p subshell, ℓ = 1 For d subshell, ℓ = 2 For f subshell, ℓ = 3 We can calculate the number of orbitals in each subshell using the formula: 2ℓ + 1

Hund’s rule – each orbital should be first filled with one electron before being paired with a second electronĪlso, you should know the number of orbitals in each subshell.

Pauli exclusion principle – two electrons with the same spin can not occupy the same orbital.

Aufbau principle – electrons are first filled in lowest energy orbital and then in higher energy orbital.

#3 Draw Orbital Diagram of Vanadiumīefore drawing the orbital diagram, you should know the three general rules. Now in the next step, start drawing the orbital diagram for vanadium.

Learn how to find: Vanadium Electron Configuration The electron configuration of vanadium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 3. #2 Write Electron Configuration of Vanadium

Since the atomic number of vanadium is 23, the total electrons of vanadium are 23.

There is no hard and fast rule for this, but that is an explanation that correlates with experimental data.The atomic number of vanadium represents the total number of electrons of vanadium. Thus, electron pairing is favorable enough for Tungsten. The more the electron distribution is spread out, the less electron-pair repulsion there is, and thus the lower #Pi_c# is. However, Tungsten's #5d# and #6s# orbitals being larger than the #3d# and #4s# orbitals (respectively) spreads out the electron density enough that the pairing energy ( #Pi = Pi_c + Pi_e#) is small enough.

The small-enough orbital size means that the electron density is not as spread out as it could be, which makes it favorable enough for a maximum total spin to give the most stable configuration.

The minimization comes from having all unpaired electrons in the #3d# and #4s# ( #3d^5 4s^1#), rather than one electron pair in the #4s# ( #3d^4 4s^2#).

The minimized coulombic repulsion energy #Pi_c# further stabilizes this configuration.

The maximization comes from how there are #5# unpaired electrons, instead of just #4# ( #3d^4 4s^2#).

The maximized exchange energy #Pi_e# stabilizes this configuration ( #3d^5 4s^1#).

One explanation for Chromium, then, is that: New criteria for assigning the spectra of these complexes are introduced and the data pro- cessed to yield a series of crystal field and molecular orbital. The former is stabilizing and the latter is destabilizing, as shown below (suppose configuration 2 is at pairing energy #Pi = 0#): These combine to produce an overall pairing energy #Pi = Pi_c + Pi_e#.The coulombic repulsion energy #Pi_c# (a destabilizing factor that is inversely proportional to the number of electron pairs).The exchange energy #Pi_e# (a stabilizing quantum mechanical factor that is directly proportional to the number of pairs of electrons in the same subshell or very close-energy subshells with parallel spins).To explain Chromium's electron configuration, we could introduce: Unfortunately, there is no easy way to explain these deviations in the ideal order for each element. Interestingly enough, Tungsten is more stable with an electron arrangement of #4f^14 5d^4 6s^2#.
