Dmitri Mendeleev was an irascible Russian chemist most famous for his work in developing the periodic table of elements. He was the youngest of 17 children and after studying to become a teacher, he took an advanced degree in chemistry in 1857. Mendeleev began his work on the periodic table in 1869 while writing a textbook. It was in this book that he began grouping elements in an ascending order according to their atomic weight (essentially relative atomic mass), noticing that chemically similar elements tended to fall into similar columns. Initially not all of the 63 known elements would fit into Mendeleev's table, and so he altered the atomic weights of indium and beryllium so that they would fit (their initial weights were somewhat inaccurate). In 1871 Mendeleev published a revised table, which ... included gaps for elements that had yet to be discovered.

Dmitri Mendeleev was a Russian chemist who in the 1800's, became famous for the discovery one of the basic principals of chemistry. He collected thousands of facts about the 63 elements that were in existence and had already been discovered at that time. Scientists working before him had concluded that groups of elements had similar chemical and physical properties. His hunch was that a pattern or order must exist in all elements. He wrote a book recording all of his discoveries. He called it properties of chemistry.

In 1869, Dmitri Mendeleev, a Russian chemist, proposed a similar idea. He suggested that the properties of the elements were a function of their atomic masses. However, Mendeleev believed that similar properties occurred after periods (horizontal rows) that could vary in length. Although he placed seven elements in each of his first two rows, he placed seventeen elements in each of the next two. However Mendeleev took it one step further in predicting that some elements may not be discovered yet and left blank spots in the periodic table. He even went so far as to predict a name and the properties of these yet to be discovered elements.

In the late 1800's Dmitri Mendeleev developed the periodic table of elements. He placed elements into the table according to its properties. Your task will be to memorize the first 100 elements in order. Just kidding. You will need to research only one element and set your new knowledge to a tune.

Dmitri Mendeleev was born in Tobolsk, Siberia, to Ivan Pavlovich Mendeleev and Maria Dimitrievna Mendeleeva (nee Kornilieva). Mendeleev was the 13th surviving child of 17 total, but the exact number differs among sources. As a child, he was fascinated by the glass which was created at the factory his mother owned, and for a time, the young Mendeleev worked there. At the age of 13, after the death of his father and the destruction of his mother's factory by fire, Mendeleev attended the Gymnasium in Tobolsk.

Dmitri Mendeleev was born in the Siberian town of Tobolsk on Feb. 8, 1834. Dmitri was the youngest of 17 children born to Ivan Pavlovich and Maria Dmitrievna Mendeleev. Dmitri’s father was the principal of a gymnasium and his mother was described as a brilliant and beautiful woman who came from a prominent Siberian family and was self-educated. In 1847, Dmitri’s father went blind from cataracts and was forced to retire on an inadequate pension. To support the family, Dmitri’s mother opened a glass factory which burned to the ground in 1848, the same year in which Dmitri’s father died.
