Using atomic number instead of atomic mass as the organizing principle was first proposed by the british chemist henry moseley in 1913, and it solved anomalies like this one iodine has a higher atomic number than tellurium - so, even though he didn't know why, mendeleev was right to place it after tellurium after all.
