Question

Name the metal of the 1st row of the transition series that has zero spin only magnetic moment in its oxidation state

Answer 1

Answer:

Scandium is the element

Explanation:

EC of scandium is [Ar] 4s2 3d1

Scandium has oxdn state of +3

So Electronic configuration at this excited state is 4s0 3d0

It has 0 unpaired electrons, hence 0 magnetic moment.
