A neutral atom in its ground state contains 28 electrons. this element is considered a transitionelement, and has 8 electrons in orbitals with l = 2. Electron configuration: ₂₈X 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s². l is azimuthal quantum number, l = 2 describes d orbital. There is eight electrons in 3d orbital.
The element in question is nickel. Nickel is a transition metal belonging to group10 in the periodic table. Its electron configuration is [Ar]4s2 3d8. Hence it has eight electrons in the d(l=2) orbital.
This is the ground state electron configuration of the transition metal nickel.
