Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

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 ...

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. When you purchase ...

The newest, heaviest element has been confirmed under laboratory conditions, and its synthesis could help produce even heavier cousins with all-new useful properties. Share on Facebook (opens in a new ...

The periodic table contains more than a hundred chemical elements, the basic building blocks of the everything around us — living and non-living. The atomic number of an element is determined by how ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...

The methods previously described have been applied to a study of the elastic scattering of 4· 2 MeV protons by deuterium, helium, nitrogen, oxygen, neon, argon, chlorine and bromine. The results ...
