X-rays allow scientists to characterize larger batches of atoms. When X-rays strike atoms, they transfer their energy into those atoms’ electrons, exciting them.

Electrons are also small enough to be used to image atoms and molecules, using a variety of techniques in electron microscopes.

We all know that atoms are made up of protons, electrons, and neutrons but an atom within an atom? Here’s how scientists created it out of strontium atoms.

Now, scientists from Austria and the US have filled in some of those gaps, creating a new state of matter in the form of "giant atoms" filled with other atoms.

That light would jostle the atoms’ electrons into higher energy states, and the accelerated atoms would emit gamma rays when the electrons later returned to lower energy states.

Scientists working on the Large Hadron Collider (LHC) achieved yet another first Wednesday (July 25), revving full-blown atoms (with electrons oribiting them) up to near the speed of light.

When it comes to our world, our Solar System, and everything we can see in our Universe, it's all made up of the same ingredients: atoms. Electrons and atomic nuclei interact and link up to form ...

After an introduction of Snap Cubes as models atoms and molecules, students use Snap Cubes to investigate the question: How can Snap Cubes be used to make models of different molecules?

Seventy years ago, in Osmond Laboratory on Penn State's University Park campus, Erwin W. Müller, Evan Pugh Research Professor ...
