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

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

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
