Webb24 juli 2024 · The nucleus of an atom is made up of protons, discovered in 1920 by Ernest Rutherford, and neutrons, discovered in 1932 by James Chadwick. Both protons and neutrons are like little spheres with a radius of 10 -15 m or a quadrillionth of a meter. Both particles are somehow stuck together in the nucleus. When the atom is heated, it … Webb11 apr. 2024 · Now, researchers at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University with collaborators at the University of Oregon and Manchester Metropolitan University have found a way to tease hydrogen out of the ocean by funneling seawater through a double-membrane system and electricity.
