1. How did the Periodic Table develop?

  • Dimitri Mendeleev, a Russian chemist, began developing the periodic table in 1869, which organizes chemical elements by atomic mass. He foresaw the discovery of new elements and provided places in his periodic table to accommodate them. Antoine Bequerel, a French physicist, discovered radioactivity in 1886.

2. Why do you think the discovery of periodic table is important?

  • The periodic table is important because it is organized to provide a great deal of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered. Without them, learning chemistry of elements and compounds will be very difficult.
