Mendeleev divided his periodic table in eight groups and seven periods. Russian chemist dmitri mendeleev holds the credit for its invention, although there were some other chemists before him working on the subject. What is truly extraordinary about this work is that the scientist predicted the existence of certain the properties of these elements were surprisingly similar to those described by dmitri mendeleev earlier, which left no doubts about the importance of.

Dmitri mendeleev has invented the periodic table which arranges all the chemical elements in a proper way that is in the order of increasing atomic predictions and gaps in this way of arranging elements mean there are gaps in his horizontal rows that are called 'periods'. When these elements were discovered, his place dmitri ivanovich mendeleev was born on february 8, 1834 in verkhnie aremzyani, in the russian province of siberia. Using his periodic table, mendeleev predicted the existence and properties of new chemical elements.
In the modern periodic table, elements are in order of atomic number in periods and groups. The heading reihen means row and the heading gruppe means group. Sendus your suggestions so we can make it better. He studied science in st. A method for organizing elements based on their atomic mass.
Scientists, Famous Scientists, Great Scientists ... from 3.bp.blogspot.com The noble gases (helium, neon, argon etc.) were not discovered until much later, which explains why there was a periodicity of 7 and not 8 in newlands table. 7 horizontal rows are called periods there are 7 periods periods represent the electron.
