Question 10 0.2 pts A diamagnetic atom or ion has no unpaired electrons in any of its orbitals, whereas a paramagnetic atom or ion has at least one unpaired electron in its orbitals. The more unpaired electrons, the more paramagnetic the atom or ion. What is the ground-state electron configuration for the ve ion and is it paramagnetic or diamagnetic? O [Ar] 4s, diamagnetic O [Kr] 5s. paramagnetic O [Ar] 3d2, paramagnetic [Ar] 4s2 3d'. paramagnetic [Ar) 4s3d 5s, diamagnetic 0.2 pts Question 11 MacBook Air F8 F7 go F5 F6 F4

Explanation / Answer

When; all electrons are paired in the compound are element then that is diamagnetic, while Para magnetism requires unpaired electrons.

The electronic configuration of V is as follows:

V:23

[Ar] 3d3 4s2

1s22s22p6 3s23p6 3d3   4s2

V3+

the electron configuration of V3+ is

[Ar] 3d2 4s0

1s22s22p6 3s23p6 3d2   4s0

There are two un-paired electron thus it is pera-magnetic.
