Choose the diamagnetic species from below. choose the diamagnetic species from below. br cr p sn2+ none of the above are diamagnetic.

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.

Answer: 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:
