School Level: 10-12 class Level of difficulty: medium Language: English Interactivity: yes Problems: none Weak points: ‌ Strong points: display of the meaning of Binomial distribution videos explain clearly the topic and can be used both for a revision of the topic, both for help to expand the knowledge.
9) Overall review 10) Example of use Students can learn that chemists describe the structure of atoms using models. This section will cover the Bohr model, photoelectric effect, absorption and emission spectra, quantum numbers, and electron configurations. The atomic models are explained in simple words and can be understood very easily, can be used either for the revision of the topic or to explain new concepts. Students can use these tutorials to understand how to write electron configurations and to see how the quantum numbers predict the orbitals available in different energy levels.

6) Problems: no 7) Weak points: There are no exercises. 8) Strong points: The videos are clear in all parts and explain in a good way ad with simple words the topics treated. There is a transcription of the videos so if someone lacks in listening skill, still can follow the lesson. The topics can be easily found from the index in the left part. 9) Overall review 10) Example of use The videos can be used either for revision or to get a deeper insight in the topics. The online video lessons in the Atom unit discuss the structure of atoms, the particles of which atoms are composed, and the interactions between these particles at the subatomic level.) http://www.chimicaonline.it/download/model lo-atomico-a-orbitali.htm

The theoretical parts are explained in simple words and they can be used as a revision in class or as a consolidation for further development.

9) Overall review 10) Example of use It can be used as a revision for the part of the models of the Hydrogen Atom. The detailed for each element can be used to expand the contents for students that want to know more about them. It explain how scientists figured out the structure of atoms without looking at them. Students can check how the prediction of the model matches the experimental results.
