Chemistry and Our Universe: How It All Works Season 1 Episode 26 Covalent Solids

In episode 26 of Chemistry and Our Universe: How It All Works, titled Covalent Solids, we explore the fascinating world of covalent bonds and the materials they create. Covalent bonds are the strongest type of chemical bond and occur when two atoms share electrons in order to fill their outermost electron shell. This creates a very strong bond between the two atoms and results in the formation of covalent solids.

The episode begins with an overview of the properties of covalent solids, which include high melting and boiling points, hardness, brittleness, and electrical nonconductivity. We then dive deeper into the science behind covalent bonding and learn about the different types of covalent bonds, including sigma and pi bonds.

We also explore some of the most common examples of covalent solids, including diamond, graphite, and silicon dioxide. Diamond is a particularly interesting example of a covalent solid because of its unique properties, such as its extreme hardness and its ability to refract light. Graphite, on the other hand, has a much more complex structure made up of layers of carbon atoms that are weakly bonded together through Van der Waals forces.

Next, we discuss the ways in which scientists are able to manipulate covalent solids in order to create new materials with unique properties. One such example is the creation of carbon nanotubes, which are long, thin tubes made up of carbon atoms that have been arranged in a particular way. Carbon nanotubes have a number of unique properties, including high strength and electrical conductivity, which make them useful in a variety of industries, including electronics and aerospace.

Finally, we explore some of the practical applications of covalent solids, including their use in electronics, semiconductors, and solar cells. We also discuss the ongoing research being done in this field and the potential for new materials and technologies to be discovered in the future.

Overall, Covalent Solids is an informative and engaging episode that delves into the fascinating world of covalent bonds and the materials they create. Whether you are a science enthusiast or just curious about the world around you, this episode is sure to provide you with a wealth of interesting information and insights.
