1. Dmitri Mendeleev Periodic table

2. Dmitri Mendeleev Dmitri Mendeleev is known for his discovery of the periodic law and the creation of the first periodic table. He created this in 1869 in St. Pertersburg, Russia. -Dmitri Mendeleev was born in Tobolsk, Russia. -He was the youngest of 17 children. -As a child, Mendeleev’s mother’s glass factory burned down -Mendeleev studied at the Main Pedagogical institute in St. Petersburg

3. Scientific Facts -Mendeleev used Chemical spectroscopy as his method -There were 63 elements on his published periodic table -He arranged his table so that every element in every column had similar chemical properties -Mendeleev had to learn how to calculate valency for his periodic table -Mendeleev listed the elements on his table in order of atomic mass -He won the nobel prize as the creator of the 1 st periodic table of elements

4. Facts About Mendeleev’s Periodic Table -It was the first published periodic table -Mendeleev created the periodic law -The table was organized by atomic number, and the structure is still used in today’s periodic table of elements -The elements in his table are organized so that elements in the same column have similar chemical properties -Mendeleev left gaps in his periodic table that helped modern scientists fill in the spaces and figure out each element’s chemical and physical properties

5. Similar elements in the same column Holes left for future scientists to fill Organized by atomic number
