Let's take a look back at the elements silicon, fluorine, lithium, boron, and chromium.

Let's take a look back at the elements platinum, iodine, aluminum, iron, and tungsten.

Dr. Brandon Reddell discusses astrophysics, cosmology, and the science behind the Alpha Magnetic Spectrometer (AMS), an experiment looking for evidence of antimatter and dark matter in the cosmos. This is part one of a three-part series...

This is a video that explains the electronic structure of atoms and ions and how it relates to their position on the periodic table. It covers the basics of electron shells, how to fill them, and how to represent an element's electronic...

Let's take a look back at the elements nitrogen, mercury, copper, magnesium, and cobalt.

Ibuprofen is another one of the most commonly prescribed drugs in the world, and is also another NSAID. It was developed in the 1960s, so let's get a closer look at ibuprofen and a similar drug named naproxen, so that we can compare...

Let's take a look back at the elements helium, tin, calcium, palladium, and lead.

Let's take a look back at the elements carbon, gold, neon, zirconium, and antimony.

This program covers part 1 of the very important topic of the atomic theory of matter. We discuss how atoms combine together to form new compounds. Students review the law of conservation of mass and how the mass of the substances at the...

We've seen that KMnO4 can oxidize alcohols and aldehydes to give carboxylic acids and ketones, but this reagent can also oxidize alkenes. The product(s) will be different depending on whether we use cold basic conditions or hot acidic...

Let's take a look back at the elements sodium, oxygen, argon, arsenic, and zinc.

This program covers the very important topic of the periodic table. We give an overview of how the periodic table is organized including the periods, groups, noble gases, metals, nonmetals, transition elements, and more. The entire...

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

This program covers the very important topic of ions and ionic charge. We begin by discussing the concept of an ion and how it relates to a neutral atom. We then discuss how to calculate the ionic charge on an atom with practical...

This program provides an introduction to chemistry. We begin by discussing how chemistry touches every part of everyday life and give several examples of basic chemical reactions that students come into contact with regularly. The entire...
