Understanding Electron Removal
According to the Madelung rule, electrons are removed from the highest principal quantum number first. In the case of Pt²⁺, the electrons are removed from the 6s and then the 5d subshells.
Configuration for Pt²⁺
After removing two electrons, the electron configuration for Pt²⁺ becomes:
- [Xe] 4f14 5d7
This reflects the loss of the single 6s electron and one of the 5d electrons, resulting in a stable configuration for the ion.
