Atomic Nucleus
In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but the...

The Past, Present, and Future of Carbon Dating | Compilation
Carbon dating is a lot more than just getting the age of a dinosaur bone. We can learn a lot about the world through its use, and it turns out, we have.

Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

Conservation of Charge in Reactions
In this video Paul Andersen explains how the charge is conserved in nuclear reactions. When elementary particles are created or destroyed in a reaction the net change in charge will remain constant. Alpha, beta -, and beta+ decay are all...
