This conclusion led to the theory that electrons exist in energy levels around the ...
WebThe story begins in 1932, with the discovery of the neutron by Sir James Chadwick, an English physicist. Until 1932, the atom was known to consist of a positively charged nucleus surrounded by enough negatively charged electrons to make the atom electrically neutral. Most of the atom was empty space, with its mass concentrated in a tiny nucleus. WebJames Chadwick did an experiment that led to the discovery of neutrons- particles with a neutral electric charge and almost the exact same mass as a proton. Before, it was thought that there were electrons in and outside of the nucleus. However, Chadwick and other researchers thought that there were particles with no charge in the nucleus.
WebChadwick 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. He was...

WebAlpha particles have two protons and two neutrons so they are positively charged. If they pass too close to the nucleus of the atoms in the gold foil, their straight path might change because the protons in the nuclei of the gold particles in the gold foil can repel alpha particles (like-charges repel) 1 comment ( 12 votes) Upvote Downvote Flag
