Niobium Electron Configuration
The electron configuration of niobium (Nb) can be represented as [Kr] 4d^4 5s^1. This indicates that the Nb atom has a total of 41 electrons distributed among its orbitals. The first 36 electrons are filled in the inner shells, which are represented by the noble gas configuration of krypton (Kr). The remaining five electrons are in the outermost shells - four in the 4d subshell and one in the 5s subshell. It is worth noting that niobium belongs to the transition metals, and its electronic configuration is typical of this group of elements.
