What is ekasilicons modern name?
Ekasilicon (Mendeleev's name for the element below Silicon, 1869) is named germanium since it was discovered (1886).Eka (from Sanskrit) means 'first' for first element downwards.
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
What element was discovered in space before earth?
This element is helium.
Was Dmitri Mendeleev able to predict undiscovered elements?
Dmitri Menedeleev was able to predict the properties of undiscovered elements because the periodic table organizes elements based on repeating properties. For example, all of the Noble Gases (the far-right column) have filled their valence electron shells and are inert gases. One could reasonably assume that if a new element was discovered that went in the noble gas column that it would be inert as well. Mendeleev used this concept to accurately predict the properties of a handful of undiscovered elements, such as Gallium and Germanium.
How can the periodic table be used to predict the properties of an element that has not been discovered?
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
What element was discovered in 1871 by Mendeleev?
The element discovered by Mendeleev in 1871 was germanium. Mendeleev predicted the existence of this element and its properties before it was actually discovered.

Ekasilicon (Mendeleev's name for the element below Silicon, 1869) is named germanium since it was discovered (1886).Eka (from Sanskrit) means 'first' for first element downwards.

Why were the elements gallium scandium and germanium important to Medeleev?
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.
Who discovered the periodic table of element?
Dmitri Mendeleev, although he did it differently we than it is right now. He pridected elements, and now, they've been discovered. Some people discovered elements Mendeleev didn't predict. Most of them were radioactive, like rutherfordium. (Of course, that element was synthetic. There are only 92 natural elements.) Mendeleev used different symbols than we do now, e.g. yttrium was Yt. The elements Mendeleev predicted were gallium, germanium, and scandium.
Which element was discovered in space before it was discovered on earth?
helium
What element was discovered in space before earth?
This element is helium.

How was germanium discovered?
In 1886 a German chemist named, Clemens A. Winkler discovered germanium. He discovered the first trace of germanium in the mineral argyrodite, while isolating it. (But germanium rarely makes distinct minerals.) He purified it to find the new element. Before this in 1871 a chemist named, Mendeleev predicted there would be a new element, that would have properties similar to the ones in silicon. His predictions were proved to be true.

What element was discovered first in modern times?
Oxygen which was discovered by Lavoisier. It was before known as flojistcated air.
What element was first discovered in space before it was discovered on earth?
The element helium was first discovered in space through its spectral lines in the sun's spectrum. It was later discovered on Earth through the analysis of uranium ores in 1895.
