Gallium and germanium were important to Mendeleev because their properties fit well into his Periodic Table, filling the gaps he had predicted based on the patterns of other elements. The discovery and confirmation of these two elements helped validate his periodic law and strengthen his periodic table's credibility.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
Mendeleev proposed that there must be missing elements, to which he gave the provisional names Ekaboron, Ekaaluminum and Ekasilicon. Scankium, Gallium and Germanpoop were discovered in 1879, 1875 and 1886, respectively, with properties very close to those predicted by Mendeleev. hey Glen
Yes; in his time not every element was known. As every element in the same column (group) has more or less the same chemical properties, he predicted there should be an element that was not yet discovered at some places. For example, under Silicon, there was a gap where he suspected that, to complete the pattern, a new element was missing; he called it eka-silicon, and correctly predicted many of its properties. The new element was found later, with properties very similar to the predictions; it was eventually called Germanium.
Gallium (Ga)
Mendeleev left spaces for undiscovered elements. He named them eka-aluminium, eka-silicon etc.
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.
Mendeleev predicted that gallium belonged to the R2O3. Gallium was not discovered until 1874. The noble gases weren't discovered until 1894 through 1899.
Mendeleev used the properties of gallium, scandium, and germanium to predict their existence before they were discovered. Their discovery and properties helped confirm the accuracy of Mendeleev's periodic table and his periodic law. This further solidified Mendeleev's contributions to the development of the modern periodic table.

Mendeleev used the term "eka-aluminum" to predict the properties of an undiscovered element that would have similar characteristics to aluminum. This was part of his periodic table where he left gaps for undiscovered elements. Eka-aluminum was later discovered and named gallium, confirming Mendeleev's periodic trends.
Dmitri Mendeleev was a Russian chemist who created the periodic table. The term "Eka aluminum" refers to the element gallium, which he predicted would exist based on gaps in the periodic table and similarities with aluminum. Mendeleev's predictions were accurate and gallium was discovered later.
he called them the actinides. they were ekaaluminium, ekaboron, and ekasilicon (aka germanium, gallium, and scandium)

The modern name of Ekaaluminium is Gallium. Mendeleev discovered Gallium in 1875. He also discovered Ekaboron (now known as Scandium), and Ekasilicon (now known as Germanium).
A: Because the element has different property as gallium arsenide.
