Mendeleev had predicted an atomic mass of 44 for eka-boron in 1871, while scandium has an atomic mass of 44.955907. In 1871, Mendeleev predicted [4] the existence of a yet-undiscovered element he named eka-aluminium (because of its proximity to aluminium in the periodic table).

This form became popular following the publication of Mendeleev's eight-column periodic table in 1871. Also shown in this section is a modernized version of the same table. Mendeleev and others who discovered chemical periodicity in the 1860s had noticed that when the elements were arranged in order of their atomic weights there was as an ...
He stayed up for three days and nights then, finally, on 17 February 1869, he fell asleep and dreamt of all 63 known elements laid out in a grand table. Dmitri Mendeleev's periodic table from 1871 with gaps (-) left for new elements. Mendeleev's table reveals the relationship between all the elements in their order:
