Periodic Table

  Dmitri Mendeleev was the first man to create a periodic table that was correctly predicted. The year was 1869 and at the age 14 his mother made him go to a collage in Russia. It took two years to get to the collage and when they finally got there Mendeleev's mother died. When he created the table he only knew forty eight elements, he predicted the atoms yet to be discovered.
