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...

Band Theory Dissection: Conduction in Various Substances

The band theory of solids is a fundamental concept in solid-state physics that explains the conduction of electricity in substances based on the arrangement of energy levels...

It's time to check out Group 14 on the periodic table, the carbon group. This includes carbon, silicon, germanium, tin, lead, and flerovium. What can we say about their properties, reactivities, and applications? Let's find out!

This nugget explains Electrical properties of solids.

Why do some substances conduct electricity, while others do not? And what is a semiconductor? If we aim to learn about engineering and technology, this will be a very important concept, so let's go through the basics now!
