Question

how many traids did Dobereiner identify from the existing elements during his time?​

Answer 1

❥︎Aɴsᴡᴇʀ

➪Tʜree triads

Döbereiner could identify only three triads from the elements known at that time (Table 5.2). Hence, this system of classification into triads was not found to be useful. Johann Wolfgang Döbereiner studied as a pharmacist at Münchberg in Germany, and then studied chemistry at Strasbourg.
