Newlands’ Law of Octaves The attempts of Döbereiner encouraged other chemists to correlate the properties of elements with their atomic masses. In 1866, John Newlands, n English scientist, arranged the then known elements in the order of increasing atomic masses. He started with the element having the lowest atomic mass (hydrogen) and ended at thorium …

Döbereiner’s TriadsIn the year 1817, Johann Wolfgang Döbereiner, a German chemist, tried to arrange the elements with similar properties into groups.He identified some groups having three elements each. So he called these groups ‘triads’. Döbereiner showed that when the three elements in a triad were written in the order of increasing atomic masses; the atomic …

We have been learning how various things or living beings can be classified based on their properties. Even in other situations, we come across instances of organisation based on some properties. For example, in a shop, soaps are kept together in one place while biscuits are kept together elsewhere. Even among soaps, bathing soaps are …
