Danton - macico1 indivis2vel e indestrut3vel

Anotacoes

• Subtopic: Danton and the Discovery of Electrons and Radioactivity Danton was considered macico, indivisível e indestrutível (massive, indivisible, and indestructible). The discovery of electrons and radioactivity marked significant milestones in atomic theory. • Subtopic: Johnson and the Discovery of Cathode Rays Johnson described the atom as a sphere with positive charge and variable electrons. This led to the discovery of cathode rays. • Subtopic: Rutherford's Model Rutherford proposed that electrons move around the nucleus, which is a central core of the atom. • Subtopic: Bob's Model Bob's model also describes electrons moving around the nucleus without gaining or losing energy. • Subtopic: Atomic Nucleus and Electron Sphere The atomic nucleus has a diameter of approximately 10^-15 meters. The diameter of the electron sphere (electrosfera) is about 10^-10 meters. • Subtopic: Charges of Electrons and Protons Electrons are smaller than protons and carry a negative charge, while protons are positive. • Subtopic: Anions and Cations Anions are negatively charged ions, with electrons larger than protons. Cations are positively charged ions, with electrons smaller than p...
