  • Objectives of directed works 


    This standard, directed at first-year science and technology students in the first semester, aims to introduce 
    them to matter and its basic components, which are the atom. And the study of various physical and chemical 
    At the end of this scale, the student will be able to...
1- Distinguish what matter is, its physical states, and its basic components
2- Different theories understand the experiments that allowed the discovery of the various components of matter
3- He applies various previous theories to radioactive nuclei and studies their effectiveness
4- Study of the Bohr atomic model


  • Directed Work Questions
