Good morning !!!! i need help please Reflect

We take for granted that the properties of the elements are neatly explained by their electronic configurations and can be summarized in the table on the first page of any chemistry book. However, the periodic table is less than 150 years old, and represents the results of many scientists' work and insight. Not all the elements had been discovered at that time (chemistry.about.com/od/elementfacts/a/timeline-element-discovery.htm, en.wikipedia.org/wiki/Timeline_of_chemical_elements_discoveries), but, understanding the reasons behind chemical behavior, Mendeleev left some blanks in his periodic table, predicting the properties and mass of the yet unknown element. His predictions were correct. Imagine dedicating all your life to science being aware that you will never witness the important discoveries that you are predicting!


Activity


Do some research on one of the incredible minds to whom we owe so much: Avogadro, L. Meyer, D. Mendeleev, J. Dobereiner, J. Newlands, etc. Present your findings and making sure your posting contains the following:

  1. The reasons you choose the scientist
  2. What did you learn from your research
  3. Sources (books, articles, websites) you collected information from
