Sn^2+

Explanation:

A specie is diamagnetic if it has only paired electrons in its outermost shell. This implies that, we must first deduce the outermost electron configuration of the species. From that, we can now make our decision regarding which of the species is diamagnetic.

Bromine:

Electron configuration:

[Ar]4s2 3d10 4p5

Not diamagnetic

Chromium:

Electron configuration:

[Ar]4s1 3d5

Not diamagnetic

Phosphorus:

Electron configuration:

[Ne]3s2 3p3

Not diamagnetic

Tin II ion:

Electron configuration:

[Kr]4d10 5s2

Diamagnetic

br is a non magnetic. hope this helps.

) pulls the ladder in the direction opposite

Explanation:

This is in line with lenz law that states that the magnetic field induced in a conductor act to oppose the magnetic field that produced it

Sn^2+

Explanation:

A specie is said to be diamagnetic if it has only paired electrons in its outermost shell. In order to know which specie is diamagnetic, write out the electron configuration of each species and note the number of paired electrons in the outermost shell. From that, we can now make our decision regarding which of the species is diamagnetic.

Bromine:

Electron configuration:

[Ar] 3d^10 4s² 4p^5

Not diamagnetic

Chromium:

Electron configuration:

[Ar] 3d^5 4s¹

Not diamagnetic

Phosphorus:

Electron configuration:

[Ne]3s² 3p³

Not diamagnetic

Sn²

Electron configuration:

[Kr] 4d^10 5s² 5p²

Diamagnetic

Non-magnetic
