It explains the physical properties of metals and non-metals.

In this video Paul Andersen explains how metallic solids form when delocalized electrons hold the positive nuclei in an electron sea. This model helps to explain the properties of metals like conductivity, shiny appearance,...

Today we’ll explore more about two of the three main types of materials that we use as engineers: metals and ceramics. We’ll discuss properties of metals, alloys, ceramics, clay, cement, and glass-ceramic materials. We’ll also look at...

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 thermal mass of an object is its ability to store or absorb heat. Things that are considered ‘difficult’ to heat generally have a high thermal mass. Brick or concrete, for example, heat up only after they’re provided with a lot...

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...

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...

The video discusses how the physical properties of substances depend on the bonding between particles. It covers ionic compounds, small molecules, giant covalent structures, metals, and alloys, and explains how the nature of the bonding...

Yes, metals can exist in gaseous forms. To illustrate, let's consider lead, which has a boiling point of 1740°C. When heated past its melting point of 327°C, lead turns into a gas at 1740°C. Another notable example is mercury, which...

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

What are the properties of Alkali metals? What is ionic bonding? What are the most reactive elements of Alkali? What is known about Lithium? Why is Lithium the least reactive? What can Lithium be alloyed with?

Periodic Table of...

Even an empty lunch sack is useful to science. You can examine it and come up with some traits. In this episode, Sabrina chats about things like malleability, hardness, conductivity, and magnetism. And all with lunch! This first series...

Beautiful Bonds: The World of Covalent and Metallic Solids

Covalent solids, also known as network solids, are materials with atoms bonded together in a continuous network by covalent bonds, resulting in large, rigid structures....

Metal excess defect due to excess cations occurs when extra positive ions (cations) are present in the crystal lattice, occupying interstitial sites to maintain electrical neutrality. To balance the excess positive charge, electrons are...

The video discusses transition metals, their properties and where they are commonly found in the periodic table. The presenter provides information on the physical and chemical properties of transition metals, including their...

This video provides an overview of the valuable and versatile element, silver. It explores its properties, uses in industries such as electronics and jewelry, its historical significance as a currency, and how it can be alloyed to...

Learn the basics about aluminium - anodising it and the uses of aluminium, when learning about metals and their reactivity as a part of environmental chemistry. Aluminium is a very reactive metal. It's protective layer of oxide is very...

This video is answering the question of are all metals conductors.

This video explains the concept of thermal conduction, which is the transfer of thermal energy through solids. The video discusses the three main mechanisms of thermal energy transfer, thermal conduction, convection and thermal...

In this video we will looks at what allotropes are, and different examples of them. The term allotrope refers to different forms of the same element. Diamond and graphite are made of only carbon atoms – yet they exhibit very different...

This video provides a brief overview of copper, highlighting its unique properties and various uses in different industries. It explores how copper is used in electrical connections, plumbing, industrial machinery, architecture, and the...

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...
