WebAs you know, all matter is made of atoms, and atoms are the smallest pieces of chemical elements. In other words, an atom is the smallest particle that displays all the properties of a chemical element. Hydrogen, oxygen, and gold are all examples of elements. Atoms consist of a nucleus and an electron cloud, as illustrated in Figure 1. WebThomson conjectured that the electron was a fundamental building block of matter or atoms, and along with his colleagues at Cambridge attempted to build upon his discovery in order to model atomic structure with theoretical speculations and extensive experimental investigations, particularly scattering experiments. birkenstock monterey leather slide sandalsWeb00:00 - How did Thomson discover electrons?00:40 - What were electrons originally called?01:13 - How did they discover the electron?Laura S.
