Please mnemonics of Dobereiner's Triads , i need it.

Dear Student,

The best way is to learn by writing and practicing. Learn and write the names and chemical symbols of all the elements for every group three to four times and you will be thorough with them. That way, you will remember more clearly and not end up getting confused. The more you practice, the more confident you become.

Looking forward to hear from you again!!


  • -7
Just remember first member of every triad. OR Remember the atomic number if first element i.e.,3,20,17. Then just write next two elements of same group
