How do you count half of a neutron? Solve the mystery of those awkward atomic masses that contain decimals with a video from JFR Science. The narrator shows viewers how to calculate the average atomic mass using the relative abundances...

How do medical professionals use radiation without doing more harm than good? Budding nuclear chemists begin their study of all things radioactive with a video from the JFR Science playlist. Topics include differences between isotopes,...

Scientists created a new measurement, the atomic mass unit, which is defined as carbon 12 = 12amu. So why isn't carbon listed as having exactly 12 amu on the periodic table? An installment from the Socratica chemistry playlist answers...

Teach the connection between isotopes and atomic mass. An engaging video demonstrates the calculation of the atomic mass of carbon when considering its isotopes. The instructor then shows the connection to molar mass.

Demonstrate the complex process of calculating a weighted atomic mass. Given the atomic mass of isotopes of a sample, the lesson instructor models the calculation. Multiple examples give learners the opportunity to review the process.

Explore the makeup of the atomic nucleus. A video lesson describes the subatomic particles of the nucleus. The instructor explains the connection between the mass and atomic numbers and the isotopes of an atom.

Atoms may make up everything, but what are they made of? The narrator asks patrons at a local park what atoms are in an interview-style video. He then creates an atomic model and adds a neutron to it, opening the discussion to isotopes.

Since an atom can't have a partial neutron, the atomic mass should always be a whole number, but it isn't! An interactive video lesson explains how the atomic mass number from the periodic table incorporates the isotopes of an element....

Create a little excitement with a radioactive resource! An engaging lesson builds a solid understanding of the nature of radioactive isotopes. The narrator explains the desire of a nucleus to become stable, which leads to radioactive...

Build an understanding of relative atomic mass based on the isotopes of an element. The video instructor leads an interactive lesson describing the process of calculating a relative atomic mass. He develops a formula through an analysis...

The facts are in the numbers! Using atomic mass units, a video lesson explains the carbon atom as the reference mass. Building from that idea, the narrator describes the relative isotopic mass.

How can atoms with different masses be the same element? An interactive video lesson describes the meaning of an isotope. The instructor emphasizes the relationship among the subatomic particles. The lesson continues by discussing...

Learn the ins and outs of the particles we call atoms. A thorough video lesson describes the atom as a building block. The instructor discusses the periodic table as a reference to atoms and then explains the parts of the atom in detail.

Hydrogen is the most abundant element in the universe. The 12th video in a 15-part series on the periodic table of elements focuses on hydrogen. It describes its role in the universe, how it appears in nature, how we use it in...

Skeletons may not be able to speak, but they can still tell us a lot. High schoolers watch a short video about the ways biological anthropologists can use a skeleton's bone structure to determine age, gender, place of birth, and social...

It's getting hot in here! Evidence of global warming is all around us, as shown in part four of a series of eight videos about global warming and the carbon cycle. High school environmentalists get to examine the facts for themselves in...
