About This Chapter
Atomic Structure & Properties of Elements - Chapter Summary
The lessons in this chapter will take you through atomic mass and number, electron configuration in the s, p, and d orbitals, and the groups and periods of the Periodic Table. You'll learn about the Pauli exclusion principle and other related rules, the de Broglie hypothesis and much more. Successful completion of the chapter will enable you to:
- Identify atomic and mass numbers and electron configurations
- Describe the interactions between light and matter
- Discuss the importance of the de Broglie hypothesis and the Heisenberg uncertainty principle
- Give examples of the angular momentum quantum number
- Explain the rules that apply to atomic structures, including Hund's rule and the Aufbau principle
- Identify properties and trends among groups and periods of the Periodic Table
This study guide is structured to help you maximize your use of time by providing you with short yet informative lessons that fit easily into your busy schedule. Each lesson is accompanied by a brief quiz, and the chapter test allows you to check your overall mastery of the information. The user-friendly, readily accessible online platform is available to you 24/7/365, so you can study at your own convenience from any device that can connect you to the Internet.
1. Atomic Number and Mass Number
Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.
2. Electron Configurations in the s, p & d Orbitals
Getting confused by long lists that start with 1s and seem to go on forever? Don't worry, this lesson on electron configuration will help you understand how to describe electron placement in no time.
3. How Light & Matter Interact
This lesson will go over the fundamental basic of how light and matter interact with one another. You'll learn about photons, excited atoms, binding energy, and energy levels.
4. The de Broglie Hypothesis: Definition & Significance
The de Broglie hypothesis states that particles of matter can behave as both waves and particles, just like light. In this lesson, we'll learn the basics of the de Broglie hypothesis and how it related to other theories released at the same time.
5. Heisenberg Uncertainty Principle: Definition & Equation
The Heisenberg uncertainty principle is one of the core concepts in quantum mechanics. In this lesson, we define the uncertainty principle and learn more about its implications for physical science.
6. Angular Momentum Quantum Number: Definition & Example
Electrons in an atom occupy regions known as orbitals, and these orbitals have shapes. In this lesson, we will discuss the secondary quantum number: the angular momentum quantum number, which determines the shape of an orbital.
7. Atomic Structures: Pauli Exclusion Principle, Aufbau Principle & Hund's Rule
This lesson discusses the three main rules that govern how electrons fit in the atomic structure by filling the shells, subshells, and orbitals. We will also review the basics of quantum numbers before learning these principles.
8. The Periodic Table: Properties of Groups and Periods
How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.
9. Ionization Energy: Trends Among Groups and Periods of the Periodic Table
Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.
