The Periodic Table

In the first episode of “Crash Course Chemistry,” host Hank Green introduces viewers to the periodic table. He explains the significance of the periodic table as a tool for understanding the properties and behaviors of different elements. Green also discusses the importance of electron configuration and how it relates to the periodic table.

Key takeaways:

– The periodic table organizes elements based on their atomic structure and properties. – Electron configuration determines an element’s chemical behavior.

Bonding and Chemical Reactions

In the second episode, Green delves into the concepts of bonding and chemical reactions. He explains the different types of chemical bonds, including ionic, covalent, and metallic bonds. Green also discusses the principles of chemical reactions, including the law of conservation of mass and the role of catalysts.

Key takeaways:

– Chemical bonds determine an element’s reactivity and behavior. – Chemical reactions involve the rearrangement of atoms and the formation of new compounds.

Acids and Bases

The third episode of “Crash Course Chemistry” is all about acids and bases. Green explains the pH scale and the differences between acids and bases. He also discusses the behavior of acids and bases in aqueous solutions and their importance in everyday life.

Key takeaways:

– Acids have a low pH and can be corrosive. – Bases have a high pH and can be caustic. – The pH scale measures the concentration of hydrogen ions in a solution.

Organic Chemistry

In the fourth episode, Green explores the world of organic chemistry. He explains the structure of organic molecules and the importance of functional groups. Green also discusses the principles of organic reactions and their applications in everyday life.

Key takeaways:

– Organic molecules contain carbon and hydrogen atoms. – Functional groups determine the properties and behavior of organic molecules. – Organic chemistry has many practical applications, including in medicine and agriculture.


The fifth episode of “Crash Course Chemistry” focuses on thermochemistry. Green explains the principles of thermodynamics and the different types of energy. He also discusses the laws of thermodynamics and their applications in chemical reactions.

Key takeaways:

– Thermochemistry involves the study of energy changes in chemical reactions. – Energy can be transferred in the form of heat or work. – The laws of thermodynamics govern the behavior of energy in chemical systems.
