Unit 2 - Atomic Structure

Atomic Structure Objectives

1.5 Atomic Structure & Electron Configuration - SAP-1.A - Represent the electron configuration of an element or ions of an element using the Aufbau principle. 

1.6 Photoelectron Spectroscopy - SAP-1.B – Explain the relationship between the photoelectron spectrum of an atom or ion and: a) The electron configuration of the species, b) The interactions between the electrons and the nucleus.

1.7 Periodic Trends - SAP-2.A – Explain the relationship between trends in atomic properties of elements and electronic structure and periodicity.

1.8 Valence Electrons & Ionic Compounds - SAP-2.B – Explain the relationship between trends in the reactivity of elements and periodicity.

3.12  Photoelectric Effect - SAP-8.B - Explain the properties of an absorbed or emitted photon in relationship to an electronic transition in an atom or molecule.

Atomic Structure Big Ideas

Big Idea 2: Structure and Properties (SAP)

• Enduring Understanding SAP-1: Atoms and molecules can be identified by their electron distribution and energy.

• Enduring Understanding SAP-2: The periodic table shows patterns in electronic structure and trends in atomic properties.  

• Enduring Understanding SAP-8: Spectroscopy can determine the structure and concentration in a mixture of a chemical species.
