Question: what is the correct electron configuration for v+?
Answer: 1 Expert Answer In shorthand, the electron configuration for V is [Ar]4s23d3 . However, when electrons are removed - I know it's weird - the s-electrons come off first. So V2+ would be [Ar]3d3 . Maybe it's to do with the shielding effects of the inner 3d, making it easier to remove the outer 4s.....
