Salt is routinely used to melt snow and ice on winter roads. But what is happening at the molecular level to cause this helpful change of state? Chemistry - Atoms And Bonding - Learning Points. When salt is added to water it lowers the...

Researchers at MIT have developed a lightweight structure of tiny blocks that can be snapped together, similar to the way child's construction toys can be put together, and revolutionize the assembly of large objects, such as airplanes,...

Giant ionic structures also have exceptionally high melting points. This is because the electrostatic interactions between the ions are very strong. Mg2+ and O2- ions have double the number of charges on their ions than Na+ and Cl- ions...

This program covers the very important topic of hydrate compounds. We begin by discussing what a hydrate compound is and why they exist in nature. We discuss how to name hydrate compounds using numerous examples. The entire lesson is...

Different ionic compounds will adopt different lattice structures, which are essentially different geometries. If we know the lattice structure of a compound and we know some information about the dimensions of its unit cell, we can do...

Now that we have covered a variety of separation techniques, we know how to get an isolated product! But if it's a solid, it may contain impurities. Recrystallization is a common organic chemistry laboratory technique for the...

We've learned a lot about covalent compounds, but we haven't talked quite as much about ionic compounds in their solid state. These will adopt a highly ordered and repeating lattice structure, but the geometry of the lattice depends...

Learn the basics about particles in a metal, that are held together by metallic bonds.What are metallic bonds? Find out more in this video!
