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 ...

Scientists have long wondered whether there is a limit to the number of protons and neutrons that can be clustered together to form the nucleus of an atom. A new study comes closer than ever to ...

The difference lies in the structure of the atom's nucleus ... with separate levels for protons and neutrons. Individual isotopes can correspondingly be singly magic, with a magic number of either ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom ...

Atoms can be more overweight than we thought, a team of scientists in the United States has discovered. They have sent atoms crashing into one another in a particle accelerator to create bloated ...

"Developed initially for space observations, the Compton Camera has now proven its worth as a tool for addressing complex scientific questions in other domains as well." When you purchase through ...

A new study suggests that the positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects. Neutron stars are the smallest, densest ...

Physicists in Switzerland are turning to a new method in the search for nature’s possible fifth force—one that might explain some of the universe’s greatest mysteries. Their work centers on atomic ...

Mrs Roberts: What do you think you're made of? Mr Spellman: Big question. Grit, determination, hard-working, handsome, charming, funny. Mrs Roberts: Well, I guess. But you're actually made of atoms.

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...
