The center of an atom, called its nucleus, consists of positively charged protons and uncharged neutrons stuck together, kind of like a droplet of water.

Explore the fascinating world of atoms in this video, which delves into their fundamental components: protons, neutrons, and ...

If an atom gets too heavy with neutrons, extra neutrons simply won't stick at all ? not even for an instant. Nuclear physicists have long been trying to map out where this boundary of stability lies.

All the elements in the Periodic Table are made from different atoms, and the structure of these atoms results in a gamut of phenomena from radioactive decay to nuclear power.

Subatomic particles Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus.

Learn what mass number and atomic number tell us about the protons, neutrons and electrons in science's current Rutherford-Bohr model of an atom.

How long can a neutron survive outside an atom? Again, fundamental physics values shouldn't change based on how you measure them.

In the end, the team observed that as the number of neutrons in an atom's nucleus increased, the probability of protons having high energies (and having paired up with a neutron) also increased ...
