This lesson utilizes an adaptation of the board game Subatomic: An Atom Building Game to help students learn about the different parts that make up an atom. During their turn, players can choose to ...

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 meter. This video also goes the basic parts of an atom (protons, neutrons, and electrons) and why the ...

New research suggests a particle inside an atom can lose mass, offering a fresh look at how matter works at the smallest scale.

Do you need a well-equipped lab to measure the size of an atom (German, machine translation)? According to [stoppi], no. You need sunflower oil, some bear moss spores, and a bit of gasoline. You’ll ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.

What do atoms look like? This is actually an impossible question to answer: Atoms are so tiny that we can't see them using light, even looking through the most powerful lenses and microscopes. The ...

Lasers produce coherent waves of light: All the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As ...

Can scientists image the motion of electrons inside atoms? It’s a challenging problem, but solving it would help us develop a more complete understanding of things like chemical reactions and the ...

Anti-hydrogen is the antimatter equivalent of the hydrogen atom. The simplest atom in our Universe, hydrogen is usually made of a single proton and a single electron. Hydrogen is also one of the most ...
