About This Chapter
Atomic Structure & Transition Elements - Chapter Summary
In this chapter on atomic structure and transition elements, engaging lessons cover subjects like oxidation states of transition metals and color changes in transition metal ions. You can also improve your understanding of bonding in coordinated compounds. After going through the lessons, you should be able to do the following:
- Discuss three rules on how electrons fit in the atomic structure
- Explain electron configurations in atomic energy levels
- Provide an example of ground state electron configuration
- Define excited state in chemistry
- List properties of transition metals
- Recall the structure of hydrated ions
- Describe how coordinated compounds are used in nature
- Share models of chelating ligands
Our expert instructors are skilled at helping you absorb concepts related to atomic structure and transition elements. If you find yourself struggling with a topic, you can use the Help feature to submit questions to the instructors. A short quiz is available for each lesson, which is a helpful tool for ensuring you can recall what you have reviewed.
1. 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.
2. Electron Configurations in Atomic Energy Levels
This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.
3. Ground State Electron Configuration: Definition & Example
The atom's electron structure is very important because it tells us about an atom's reactivity, and physical properties as well. In this lesson, we will cover the ground state electron configuration, which determines the electron's structure.
4. Excited State in Chemistry: Definition & Overview
This lesson defines excited states of electrons within atoms and their significance in chemistry. Learn about this state, see several examples, and complete the brief quiz.
5. Transition Metals: Definition, List & Properties
The heart of the periodic table is home to some of the most famous metals, the transition metals. Learn the definition of a transition metal, look at a list of them, and learn some of their properties. Then, assess your knowledge with a quiz.
6. Oxidation States of Transition Metals
Transition metals can be a little confusing, but this lesson will simplify things by explaining why transition metals can have more than one oxidation state. It will also touch on other topics such as half equations and colored solutions.
7. Hydrated Ion: Definition, Structure & Examples
What happens when salt is placed in water? In this lesson, we will explore the hydration of ions, or what happens when ionic solids dissolve in water and further talk about ions that even form complexes with water in the solid phase.
8. Coordination Chemistry: Bonding in Coordinated Compounds
Discover what a coordinated compound is. Understand how bonding occurs in coordinated compounds and some of the possible shapes coordinated compounds can be. Learn the uses in nature and industry for coordinated compounds.
9. Chelating Ligands: Definition, Models & Examples
This lesson will introduce chelating ligands, which are ligands with more than one donor site. It will provide the structures of some common ligands and go over nomenclature and the properties of chelate compounds.
