Although Dobereiner`s triads could not group all elements according to their properties, they said the basis for the formation of the modern periodic table. The boundaries of the Doberone triads were as follows: (v) the elements of the s-block with 1 valence electron are called alkali metals. WebIt was later identified as gallium. Gallium, germanium, and scandium were all unknown in 1871, but Mendeleev left spaces for each and predicted their atomic masses and other chemical properties. Within 15 years, the “missing” elements were discovered, conforming to the basic characteristics Mendeleev had recorded.
