Scientists have been slowly extending the periodic table one element at a time, pushing to higher and higher masses, and have discovered some incredibly useful materials along the way. But the elements at the current end of the table are...

If you look at a copy of the periodic table, you might notice that basically every element after lead is labelled as radioactive. And the vast majority of those elements wind up decaying into some version of lead eventually. But why is...

Our universe seems pretty complicated. We have a weird zoo of elementary particles, which interact through very different fundamental forces. But some extremely subtle clues in nature have led us to believe that the forces of nature were...

Two protons next to each other in an atomic nucleus are repelling each other electromagnetically with enough force to lift a medium-sized labradoodle off the ground. Release this energy and you have, well, you have a nuclear explosion. ...

This video is about the Ozma problem of distinguishing the chirality (ie left-handedness or...

SciShow explains radiocarbon dating, the best way to date a dead thing!

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...

It's time for our second to final Physics episode. So, let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it so useful to us as physicists and humans? In this episode of Crash Course Physics, Shini sits down...

Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.

In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the...

Are Neutrinos useless? Would we exist without neutrinos? What are neutrinos? And what purpose do they serve? Where do Neutrinos come from?



They are the second most abundant particles after photons. They do...

SUMMARY:

Quantum field theory or QFT is the basis of the best theory we have in physics today to explain nearly everything, called the Standard Model of particle physics. What is Quantum Field theory? Why is it...

In this video, I summarize All Nuclear Physics in about 10 minutes. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The nuclei of atoms are made up of protons and neutrons. These are called...

This video covers: - What alpha, beta and gamma radiation are - How to write decay equations for them General info: - Suitable for all GCSE and IGCSE courses - Suitable for higher and foundation tiers - Suitable for triple and combined...

Neutrons and Isotopes describes how neutron loss or gain affects the stability of an atom by using terms such as isotope, atomic mass, unstable, and decay.

Learn about the different types of radiation in this physics video from the virtual school. Alpha particles, beta particles and gamma rays... what are they and how do they differ?



Introducing 'Alpha Man', 'Beta Boy' and 'The...

This nugget explains the concept of radioactivity, its types and mathematical expressions and examples.

Radioactivity. We've seen it in movies, it's responsible for the Ninja Turtles. It's responsible for Godzilla. But what is it? It's time to learn exactly what nuclear reactions are, and what it is that makes atomic bombs so destructive,...

Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many...

When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...
