In nuclear physics, "magic numbers" identify specific numbers of protons or neutrons that lead to especially stable nuclei. Recognizing these numbers helps scientists better understand the ...

Based on nuclear mirror symmetry, theorists predicted that proton number 14 should also be a magic number in its mirror nucleus, silicon-22 (8 neutrons and 14 protons).

The electrons each carry one unit of negative charge, the protons each carry one unit of positive charge, and the neutrons have no charge. An atom has the same number of protons as electrons, so it is ...

Almost everything on Earth is made up of atoms, but where do these fundamental building blocks come from?

All matter is made of atoms, which in turn are made up of protons, neutrons and electrons. The number of protons is what gives atoms their chemical properties, setting apart the various chemical ...

The extremely heavy hydrogen isotopes ⁶H -- consisting of one proton and five neutrons -- and ⁷H -- with one more neutron -- have the highest neutron-to-proton ratios known so far.

Neutron stars are some of the most exotic and active objects in the universe, even if they're technically dead.

All the oxygen in your body is thanks to magic numbers of protons and neutrons in the nucleus.

Is there exactly the same number of electrons as there are protons in the universe? Is that also true of Earth at any given moment? Eric Kvaalen Les Essarts-le-Roi, France In most stars, hydrogen ...

Key Concepts Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the ...
