Question

What is a diamagnetic ion?

Answer 1

We have to know that, at the point when two electrons are combined in an orbital to such an extent that their complete twist is equivalent to nothing, then, at that point it is known as a diamagnetic iota. In different cases, on the off chance that electrons are unpaired, the iota is called paramagnetic.

Complete answer:
We have to know that, in science, to be diamagnetic shows that a substance contains no unpaired electrons and isn't drawn to an attractive field. Diamagnetism is a quantum mechanical impact that is found in all materials, yet for a substance to be named diamagnetic it should be the solitary commitment to the matter's attractive impact.
A diamagnetic material has a penetrability not exactly that of a vacuum. On the off chance that the substance is set in an attractive field, the course of its prompted attraction will be inverse to that of iron, creating a terrible power. Conversely, ferromagnetic and paramagnetic materials are drawn to attractive fields.
Diamagnetism is found in water, wood, most natural particles, copper, gold, bismuth, and superconductors. Most living creatures are basically diamagnetic. $N{H_3}$ is diamagnetic in light of the fact that every one of the electrons in ammonia are combined.
Generally, diamagnetism is so feeble it must be recognized by exceptional instruments. Notwithstanding, diamagnetism is sufficient in superconductors to be promptly evident. The impact is utilized to cause materials to seem to suspend.

Note:
Another show of diamagnetism might be seen utilizing water and a super magnet. On the off chance that an incredible magnet is covered with a layer of water that is more slender than the distance across of the magnet, the attractive field repulses the water. The minor dimple framed in the water might be seen by appearance on the water's surface.
