Google honours Russian chemist Dmitri Mendeleev with doodle on his birth anniversary
Today's doodle on the homepage of the search engine giant Google celebrates the 182nd birth anniversary of renowned Russian chemist Dmitri Mendeleev who had formulated the periodic table. The simple doodle has the scientist with a redesigned logo of Google showing part of his periodic table chart.

It may be recalled that Mendeleev's periodic table was published in 1869 that organized 63 known elements till then based on their atomic mass with missing gaps for the elements yet to be discovered. An element with atomic number 101 discovered later was named Mendelevium to honour the creator of the periodic table in 1955

In a statement Google has said, "Mendeleev used the logic of his table to argue for the existence of yet-to-be discovered elements (like gallium and germanium), and even to predict their behaviors. Some of these predictions were wrong, but the basic principles behind his periodic organization continue to stand at the foundation of modern chemistry."

Dmitri Ivanovich Mendeleev (1834-1907; born: Tobolsk, Russia, Russia) formulated the Periodic Law which was converted to periodic table of elements to predict missing elements and their properties.

After creation of periodic table, Mendeleev spent many years teaching chemistry at higher education level and researching the thermal expansion materials and the nature of petroleum. Later, he became the Director for the Bureau of Weights and Measures in St. Petersburg.
