Electron configuration is the distribution of electrons in the orbits of atoms or molecules. The electronic configuration of nickel is: 1s 2 2s 2 2p 6 3s 2 3p 6 3d 8 4s 2 or you can also write it as [Ar] 3d 8 4s 2. The electrons located in the outermost shell are considered as valence electrons. In the case of nickel, there are 2 electrons present in the 4 th or outermost shell. So, valence electrons of nickel are 2. It has the atomic number 28 and the symbol Ni.
The metal form of Nickel looks silvery lustrous along with possible tinges around. In the periodic table Nickel is a transition metal and hence it shows similar properties. Nickel is one of the oldest, but useful chemical elements in science. The first use of Nickel goes back to BCE from the crust of the earth. Nickel in the present scenario has numerous industrial usage. Further, the chemical element even possesses anti-corrosion properties.
The production industries typically use the Nickels as their key component. It has vast usages in the production of stainless steel, alloys, batteries, etc. This is the reason that why the demand for Nickel remains highly significant. Thus, Nickel contributes in the assembly of usable lithium-ion batteries. Well, there are probably many ways of figuring out the valence electrons of Ni.
