Question

Learning Goal: 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 Zn2+ Express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. For example. [He]2s22p2 should be entered as [He] 2s^22p^2. submit my answer show answer review part Cr3+ Express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. For example. [He]2s22p2 should be entered as [He] 2s^22p^2. submit my answer show answer review part Ti4+ Express your answer in condensed form in order of increasing orbital energy as a string without blank space between orbitals. For example. [He]2s22p2 should be entered as [He] 2s^22p^2.

Explanation / Answer

Zn2+ - [Ar]3d10 Cr3+ - [Ar]3d3   (Cr0 is [Ar]4s13d5) Ti4+ - [Ne]3s23p6
