Electron Configuration for Chromium (Cr, Cr2+, Cr3+)
Electron Configuration Notation: -shows the arrangment of electrons around the nucleus of an atom. Once we have the configuration for Cr, the ions are simple, chromium dissertation. When we write the configuration we'll put all 24 electrons in orbitals chromium dissertation the nucleus of the Chromium atom, chromium dissertation.
In writing the electron configuration for Chromium dissertation the first two electrons will go in the 1s orbital, chromium dissertation. Since 1s can only hold two electrons the next 2 electrons for Chromium go in the 2s orbital.
The next six electrons will go in the 2p orbital. The p orbital can hold up to six chromium dissertation. We'll put six in the 2p orbital and then put the next two electrons in the 3s, chromium dissertation. Since the 3s if now full we'll move to the 3p where we'll place the next six electrons.
We now shift to the 4s orbital where we place the remaining two electrons. After the 4s is full we put the remaining four electrons in the 3d orbital and end with 3d4, chromium dissertation. Therefore the expected electron configuration for Chromium will be 1s 2 2s 2 2p 6 3s 2 3p 4 4s 2 3d 9. Note that when writing the electron configuration for an atom like Cr, the 3d is usually written before the 4s. Both of the configurations have the correct numbers of electrons in each orbital, it is just a matter of how the electronic configuration notation is written here is an explanation why.
Therefore we have still incorrect 1s 2 2s 2 2p 6 3s 2 3p 6 3d 4 4s 2. Half-filled and fully filled subshell have got extra stability. Therefore, one of the 4s2 electrons jumps to the 3d5 so that it is half-filled see video below.
This give us the correct configuration of:. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds. Intro to Electron Configurations Method 1: Using only the Periodic Table Chromium dissertation 2: Using the Electron Config.
NOTE: Chromium is an exception to the rules for writing electron configurations!
