Bohr's Atomic Model - Part 1

The Bohr atomic model, also known as the shell model, is explained. The focus of this video is on the facts you need to know for school. How Bohr came to the atomic model is explained in another video - Part 2. Original: "Chemistry and biology - get it!" Original: German. All translations in this

How Do You Split An Atom?

There are certain scientific concepts out that that most people have heard of, but don’t quite know what it implies. While you’ve doubtlessly heard mention of splitting an atom in school or films, you may have missed out on how exactly this can be done. So let’s explore the wonderful world of nuclea

The naked truth about scientific models

What is a scientific model and what is it good for? As a prelude to talking about dose-response models on Risk Bites, this week's video is a primer on models -- what they are, and why they are useful. This is part of a series of Risk Bites videos that tackle dose response and response models. Ch

08 The Atomic Shell

In this screnncast, Bohr's atomic model is compared with the energy stage model. Using the aluminum atom as an example, the different energy levels are explained and how they are to be filled with electrons are described. Original: "Wolfgang Dukorn" Original: German. All translations in this video

Three rules of thumb for using scientific models

How do you make sense of scientific models without falling into common traps? Here are three rules of thumb. This is part of a series of Risk Bites videos that tackle dose response and response models. This week's Risk Bites team: David Faulkner (post-production) Andrew Maynard (all the other stu

Atoms: The Space Between

This video segment adapted from A Science Odyssey uses models, vivid descriptions, and analogies to explain the structural integrity of matter at the atomic level. You wouldn't know it by looking at it, but the atoms that make up a solid piece of iron contain more space than stuff. How is it then th
