Well, we believe that just knowing the answer of Chromium electron configuration in itself is not enough. How Many Valence Electrons Does Chromium Have? This is the standard electron configuration of the Chromium after applying the election configuration formula. So, with the same process, the electron configuration of the Chromium will actually be 1s22s22p63s23p44s23d9. What Is The Electron Configuration of Chromium? This is a mandatory scientific process in the domain of chemistry and every chemical element has to go through this process. Chromium electron configuration in an easy language is basically the process in which the chemical element distributes its electrons in a given system of orbitals. Well, the term electron configuration is nothing new to the scholars of chemistry, however, it may a bit technical to others. You can easily witness its significance in several local or international production factories such as in the steel industries etc. For the same reason, it’s one of the highly popular and demanded chemical elements in the world. It’s one of those chemical elements that have very high practical relevance in the industrial domain across the world. The chemical element belongs to the category of group 6 and is the first chemical element of the same category. It has the representation symbol of Cr along with the atomic number 24. And the 4s subshell has one electron (instead of two electrons).Well, Chromium is basically a chemical element in the domain of chemistry that’s studied by scholars in the periodic table. That’s why the 3d subshell has five electrons (instead of four electrons). Question: Why does the 4s subshell have only one electron (instead of two electrons), and the 3d subshell has five electrons (instead of four electrons)?Īnswer: A half-full 3d subshell is more stable than a partially filled 3d subshell. That’s it! This is the final orbital diagram of chromium as we have used all 24 electrons. Hence, draw the blank orbital diagram of chromium up to 3d subshell as follows:įive arrows drawn in 3d box represent 3d 5 So each s subshell has one orbital, each p subshell has three orbitals, each d subshell has five orbitals, and each f subshell has seven orbitals.Īs mentioned above, the electron configuration of chromium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 3d 5. 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 Chromiumīefore drawing the orbital diagram, you should know the three general rules. Now in the next step, start drawing the orbital diagram for chromium. The electron configuration of chromium is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 3d 5. ![]() #2 Write Electron Configuration of Chromium Since the atomic number of chromium is 24, the total electrons of chromium are 24. The atomic number of chromium represents the total number of electrons of chromium. ![]()
