Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another ...

The world’s largest atom smasher has conducted its first-ever collisions between protons and oxygen ions, as part of an ...

The Large Hadron Collider (LHC) has begun its first-ever collisions of oxygen ions, in the latest attempt to understand the ...

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

The study shows how moving protons in water-based batteries can make them safer, faster to charge, and able to store more ...

The Large Hadron Collider (LHC) gets a breath of fresh air as it collides beams of protons and oxygen ions for the very first ...

Chadwick repeated their experiments but with the goal of looking for a neutral particle -- one with the same mass as a proton, but with zero charge. His experiments were successful.
