PPT 2.2 Electron configuration

PPT 2.2 Electron configuration has the following keywords: Electron Configuration,Quantum,Uncertainty,Orbitals,Momentum,Probability,Wave,Aufbau,Node

This PPT 2.2 Electron configuration aligns with the IB Diploma Chemistry Guide. It covers the past paper questions on this subtopic.

Objectives: This PPT enables the students to apply their learning to : differentiate between the shapes of atomic orbitals of s and p sub shells. The students can use Hund’s rule, Pauli exclusion principle and Aufbau rule to write the electronic configuration of atoms.

Though IB does not ask to learn quantum numbers but it helps to understand the whole concept. Students can relate the existence of particular sub shell in a shell with quantum numbers. Students can differentiate between different set of electromagnetic spectrum. They can differentiate between absorption and emission spectrum. They can differentiate between line and continuous spectrum.

Guidance: You can find the electromagnetic spectrum with wavelengths in the data booklet in section 3. Students need not to know the names of Lyman, Balmer etc series in the hydrogen spectrum. Students should learn condensed, full as well as orbital diagrams of electronic configuration.

Students should know the Exceptional cases of Cu and Cr where 3d4 changes to 3d5 due to the symmetrical energy aspect.
