Ferromagnetic materials, such as Fe and Ni, exhibit permanent magnetism even when the magnetic field is removed. These materials are formed by the spontaneous alignment of magnetic moments due to unpaired electrons in the same...

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...

In order to develop clean energy technology, specific rare earth metals like cobalt and nickel need to be harvested. These often come at a steep human and environmental cost– but what if there was another way? Some propose sourcing these...

Ever wonder what a metal is?

Countries like China, the US, and Russia are setting their sights on the Moon. But is it purely for the advancement of mankind, or is there profit to be found? Mining for Helium-3, metals and rare-earths on the Moon might be closer than...

Mars has a lot of the nutrients needed for plants to grow, but it also has some added extras, including toxic perchlorates. How will future missions overcome these challenges?

Atomic Models: Centuries ago, people didn’t know exactly what was inside an atom, but they had some “ideas”. Around 400 BC, a Greek philosopher named Democritus came up with a theory that everything in the world was made of tiny...

Valence electrons are the electrons that are located in the outermost shell of an atom. In other words, these are the electrons that can be gained or lost during a chemical reaction. In order to determine the number of valence electrons...

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...
