In this video Paul Andersen explains how atoms are conserved in a chemical reaction. This can be seen in a chemical equation where the subscripts represent the atoms in the molecule and the coefficients represent the molecules. The mass of an anylate can be determined through both gravimetric analysis and a titration.

In this video Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms (including chemical, mechanical, light, electrical, and thermal). In AP Chemistry students must be accountable for interactions involving an increase in volume over time.

There has been debate about whether the periodic table's newest element should have the symbol Cp or Cn? This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Here's a new video about copper, including a nice demonstration and some stories from The Professor. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because of differences in charge.

In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by graphing the potential energy versus the distance between atoms. Atoms that share electrons unequally form nonpolar covalent bonds.

In this video Paul Andersen explains how covalent network solids form elementally (like graphite) or by combining multiple nonmetals (like quartz). Covalent network solids contain elements from the carbon group because they have four valence electrons and can create three-dimensional shapes.

The video resource "The Creation of Chemistry - The Fundamental Laws: Crash Course Chemistry #3" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

We're in Germany for a new and improved video about element 110, showing you exactly where it was created. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.

Very Fast Death Factor (Anatoxin-a) is found in many forms of blue green algae.

Guy Fawkes Night in the UK is a time for bonfires and fireworks. Here's some "death mix" to shed light on things.

In this video Paul Andersen describes the intermolecular forces associated with dipoles. A dipole is a molecule that has split charge. Dipole may form associations with other dipoles, induced dipoles or ions. An important type of dipole-dipole forces are hydrogen bonds.

The video resource "Doing Solids: Crash Course Chemistry #33" is included in the "Chemistry" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

Mr. Andersen shows you how to draw Lewis Dot Diagrams for atoms and simple molecules.

In this video Paul Andersen explains how you can drive non spontaneous processes by adding external energy (like electricity or light) or by coupling it to a spontaneous process (like the conversion of ATP to ADP).

Dubnium seems to be an element no-one knows much about. This video is one of the 118 clips included in the periodic table of elements themed collection created by Brady Haran and the University of Nottingham in the UK.
