Besides the case of iodine and tellurium, later several other pairs of elements (such as argon and potassium, cobalt and nickel) were known to have nearly identical or reversed atomic weights, thus requiring their placement in the periodic table to be determined by their chemical properties.

Selain kasus yodium dan telurium, kemudian beberapa pasangan unsur lainnya (seperti argon dan kalium; kobalt dan nikel) diketahui memiliki bobot atom yang hampir sama atau terbalik, sehingga membutuhkan penempatannya dalam tabel periodik agar ditentukan oleh sifat bahan kimianya.
