Dmitri Mendeleyev Research Paper
Dmitri Mendeleyev was born in 1800s. He was a Russian chemist. He devolved and learned about the periodic table. He was an author of the book Principles of Chemistry. Dmitri also was a chemist professor.
Dmitri Mendeleyev was born in Siberia. He was born on February 8, 1834. He was the youngest of seventeen children. His father went blind when he was only thirteen. His father was a teacher at Saint Petersburg’s Main Pedagogical Institute. Both of Mendeleyev’s parents died before he was 15.
Mendeleyev at age 16 moved to Saint Petersburg, where his father taught at.

He couldn’t find a textbook adequate for his students’ needs and so he decided to produce his own book, Principles of Chemistry (1868-1870). His book won him international renown, it was translated into English in 1891 and 1897. He also created the periodic table. He had an advanced degree in chemistry by the age of 22.
His first Periodic Table was compiled on the basis of arranging the elements in ascending order of atomic weight and grouping them by similarity of properties. He predicted the existence and properties of new elements and pointed out accepted atomic weights that were in error. It was a combination of 26 letters. He wrote the names of 65 elements on card. The elements are in order by atomic weight.
Many people didn’t believe in Mendeleyev’s Periodic Table. Claiming a new element meant identifying its unique chemical properties, but finding the atomic weight so it could be fitted into the periodic table. Elements have been arranged on the periodic table according to their atomic numbers. Until the radioactive atoms could be sorted out with traditional chemistry, some scientists were reluctant to call them new
