Mendeleev was the first to successfully place a large number of compounds in a systematic way. He also predicted characteristics of some uninvented elements.
Drawback- He placed some elements with larger atomic mass before elements of smaller atomic mass.
He used atomic mass to arrange them and hence their properties didn't match quite well.
