Explain the electron configuration of cations

Assignment Help Chemistry
Reference no: EM13225953

In the transition metals (the d-block), the electron configuration of cations is different than what you might expect. Instead of the d electrons being lost first, s electrons are lost first. For example, the electron configuration of iron, Fe, is [Ar]4s23d6; but the electron configuration of Fe2+ is [Ar]3d6; the 4s electrons are eliminated to make the cation. Write out the electron configurations of

(a) Zn2+

(b) Pt2+

(c) Cr3+

(d) Ti4+
