  • Discovery of electro

    Discovery of electro
    Cathode rays are formed by particles with very low masses and negative electric charges,called electrons,which are present in all atoms

  • Rutherford’s model

    Rutherford’s model
    The atom consists of a very small part,called nucleus posotively charged and containing almost all of the mass.Around the nucleus,in the cortex,electrons move . The átomos electrically neutral.

  • Bohr’s model

    Bohr’s model
    The electrons are in electronic layers,rotating in well-defined and stable circular orbits.In these orbits,the electron does not absorb or emit energy, but it can jump from one orbit to another

  • Radioactivity

    Radioactivity
    The spontaneus emission of radiation by some substances that are radioactive is called radioactivity. They are three types of radioactivity:alpha,beta and gamma

  • The actual model

    The actual model
    With the ideas accumulated o ver the years,the scientist proposed the mechano-quantum model,valid today
