In a groundbreaking achievement, physicists have successfully peered inside the nucleus of a molecule using electrons as a ...

The pulse of an atom's magnetic heart as it ticks back and forth between quantum states has been timed in a laboratory. Physicists used a scanning tunneling microscope to observe electrons as they ...

This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

QUESTION: Is an atom really hard to break? ANSWER: Not really — we can slice them, dice them, or smash them. Let me explain a little about an atom first, and you will know what I mean. The center of ...

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom.

MIT scientists used radium monofluoride atom to observe electrons entering atomic nuclei, revealing new details of nuclear magnetism.

Famously sneaky particles have been caught behaving in a new way. For the first time, scientists have detected neutrinos scattering off the nucleus of an atom. The process, predicted more than four ...

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.
