- Döbereiner
- Döbereiner's theory was called the 'Law of Triads'
- This claimed that the appearance and reactions of elements in a triad were similar to each other
- It was one of the first attempts to order the elements in some way
- Döbereiner realised that the atomic mass of the middle element was close to the average of the atomic masses of the two other elements
- Scientists then realised how important atomic masses were when ordering elements
- Döbereiner also ordered the elements based on the similarity of their chemical properties
- For example: lithium, sodium and potassium all...
- React with water at room temperature
- React with chlorine to form similar compounds
- Combine with hydrogen to form similar compounds
- Form hydroxides with similar formulas
- For example: lithium, sodium and potassium all...
