Then, in 1869, a Russian chemist and teacher, Dmitri Mendeleev, published a table of the elements (the N-14 table to the right). Later that year, a German chemist, Lothar Meyer, published a nearly identical table. Mendeleev was given more credit than Meyer not because he published his table first and because he was better able to explain its usefulness. How did Mendeleev arrange elements in his periodic table? Look at Mendeleev's periodic table. Look at the column that starts with Ti = 50. No the two question marks between the entries for Zinc (Zn) and Arsenic (As). Why did Mendeleev leave these spaces blank? How did leaving these spaces blank, help convince other scientists that Mendele periodic table was a powerful tool?
