The properties of eka aluminum predicted by
Webbfor gallium and germanium are eka-aluminum and eka-silicon, where the eka, Sanskrit for one, has the sense of beyond. The prediction for the existence of these elements was made by Mendeleev in a paper in 1869, and it was the identification of these elements in 1875 and 1886 that made him famous, and led to the general acceptance of the periodic WebbSeveral other attempts has made to group parts together over the coming decades. In 1829, Johann Döbereiner recognised triads of elements at chemistry similar properties, such as lithium, sodium and gallium, and showed that who properties are the average element could be predicted from the properties of the other two.
