What element did Mendeleev predict before it was 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.
What element did mendeleev call ekasilicon?
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
Which element does gallium have more in common with germanium or indium?
Gallium has more in common with indium as they are both metals whereas germanium is a metalloid.
Mendeleev's decision to leave gaps in his perodic table was supported by the discovery of?
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.
What element is located in group 8 period 4?
Gallium (Ga)

What describes mendeleev use of the term eka-aluminum?
Gallium was named eka-aluminium by Mendeleev.

What element was discovered in 1871 by Mendeleev?
Mendellevium
Which element does gallium have more in common with germanium or indium?
Gallium has more in common with indium as they are both metals whereas germanium is a metalloid.
What did mendeleev call his as-yet-undiscovered elements?
he called them the actinides. they were ekaaluminium, ekaboron, and ekasilicon (aka germanium, gallium, and scandium)
What is the modern name of ekaaluminium?
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).

Why germanium and silicon are not preferred in LEDs?
A: Because the element has different property as gallium arsenide.
What element is located in group 8 period 4?
Gallium (Ga)
Which elements did Mendeleev leave space for in his first periodic table?
Mendeleev left spaces for undiscovered elements. He named them eka-aluminium, eka-silicon etc.
What does G mean on the periodic table?
There is no element with the symbol "G." There is Gallium (Ga) and Germanium (Ge).
