Detailed Solution
Download Solution PDF- डोबेराइनर ने तीन तत्वों के समूह बनाए जिनमें से प्रत्येक में समान रासायनिक गुण थे और उन्हें त्रिक कहा जाता था।
- डोबेराइनर ने त्रिक में 3 तत्वों को परमाणु द्रव्यमान के बढ़ते क्रम में व्यवस्थित किया और दिखाया कि मध्य तत्व का परमाणु द्रव्यमान दो तत्वों के परमाणु द्रव्यमान के औसत के बराबर था।

त्रिक |
तत्व-1 |
तत्व– 2 |
तत्व- 3 |
