Final answer:
The electron configuration of vanadium is 1s²2s²2pâ¶3s²3pâ¶3d³4s². The noble gas (ground state) electron configuration that is used to represent the arrangement of electrons in vanadium is [Ar]3d³4s².
Step-by-step explanation:
The electron configuration of vanadium is 1s²2s²2pâ¶3s²3pâ¶3d³4s². The noble gas (ground state) electron configuration that is used to represent the arrangement of electrons in vanadium is [Ar]3d³4s². The noble gas configuration represents the electron configuration of the nearest noble gas element, which in this case is argon (Ar). By using the noble gas configuration, we can simplify the electron configuration of vanadium and easily determine the arrangement of its electrons.
