Answers of Quiz 2270 (Dmitry Mendeleev)
1. On 8 February 1834 in Russia
2. "On the Combinations of Water with Alcohol"
3. John Newlands described a Law of Octaves, noting their periodicity according to relative atomic weight in 1864, publishing it in 1865. His proposal identified the potential for new elements such as germanium. The concept was criticized and his innovation was not recognized by the Society of Chemists until 1887.
4. Another person to propose a periodic table was Lothar Meyer, who published a paper in 1864 describing 28 elements classified by their valence, but with no prediction of new elements.
5. In 1869
6. He arranged the chemical elements in the increasing order of atomic masses and put forward a Periodic Law which stares that "The physical and chemical properties of elements are a periodic function of their atomic weights."
7. 8 groups
8. 12 periods
9. Dmitry Mendeleev
10. Organic Chemistry, Principles of Chemistry (two volumes, 1868–1870)
11. On 2 February 1907
