Скачать или смотреть Lecture 2 Electronic configuration of 3d series chapter 6 Transition Elements New Syllabus

This second lecture in Chapter 6 (Federal Board) dives deep into the electronic configuration of the 3d series elements, spanning from Scandium (Z=21) to Zinc (Z=30).
We'll cover the fundamental rules governing the filling of orbitals (Aufbau Principle, Hund's Rule, and Pauli Exclusion Principle) and specifically focus on how these rules apply to the 3d and 4s orbitals. Learn to predict and write the accurate electronic configurations for all ten elements.
Key concepts covered include:Order of filling of 4s and 3d orbitals.Understanding the exceptions in the configuration of Chromium (Cr) and Copper (Cu) and the reason behind them (stability of half-filled and completely filled orbitals).1 Relating electronic configuration to the position and properties of the 3d transition elements.
