What is the proper electron configuration for cobalt?
To write abbreviated electron configurations you need to start at the selected element and go down in atomic numbers to find the next smallest noble gas. Write the symbol for this noble gas in [brackets] then pick up writing the electron configuration like you would if you were writing a full electron configuration.
The electron configuration for cobalt is 1s2 2s2 2p6 3s2 3p6 3d7 4s2. The first number in each group identifies the energy level of the electrons. The letter represents the type of shell in which the electrons sit, while the final number denotes the number of electrons in the shell.
The electron configuration for cobalt can be shortened to [Ar] 3d7 4s2, where [Ar] represents the electron configuration for the element argon, which is equal to the first five terms in the full electron configuration for cobalt. The electron configuration for an element can be determined based on…[Xe] 6s² 4f¹⁴ 5d⁴
Tungsten/Electron configuration [Ar] 4s2 3d7.
Cobalt atoms have 27 electrons and the shell structure is 2.8. 15.2. The ground state electron configuration of ground state gaseous neutral cobalt is [Ar]. 3d7.
