Switching Locations: Understanding Frenkel Defects

In the event that an ion is absent from its lattice site, resulting in a vacancy or a hole in that location, and it occupies an interstitial site, the compound will be able to...

Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

The Schottky defect and its consequences

Ionic crystals of type A B exhibit a Schottky defect, where an equal number of anions and cations are absent from lattice sites to maintain electrical neutrality. This defect is present...

In this video students will make observations to identify materials based on their properties. Students will set up their own experiment in which they will identify the properties of ten types of matter. The video correlates to the Next...

We've learned about ionic and covalent bonds, so we understand the interactions that will occur between a metal and a nonmetal, or between two nonmetals. But what about two metals? Metallic bonding! This ends up being sort of like ionic...

The pirates are off to find more treasure! Will they make it across the stormy seas? This lesson will survey the physical properties of metals, non-metals and metalloids. Definitions included: physical property, standard ambient...
