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 ...

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

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.

HEISENBERG has discussed the hypothesis that the nucleus of an atom is composed of neutrons and protons only, the neutron being regarded as a fundamental entity and not as a combination of an electron ...

Physicists in Finland have created a pumpkin-shaped atomic nucleus that throws off protons in a rare kind of radioactive decay. The nucleus, lutetium-149, has the shortest half-life of any of a group ...

Curious Kids is a series for children of all ages. If you have a question you’d like an expert to answer, send it to ...

New research uncovers leading mechanisms of separation of active from inactive fractions of the genome in the cell nucleus and turns our picture of the nucleus upside down. Spatial separation of ...
