eka aluminum is gallium eka boron is scandium eka silicon is germanium
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
Aluminum, of course. Silicon is a metalloid while Aluminum is a metal.
Some examples of metalloid elements include silicon, arsenic, boron, and germanium. These elements have properties that are between metals and nonmetals, such as being semi-conductive and having varying degrees of metallic and non-metallic behavior.
Glass is primarily composed of silicon dioxide (SiO2), commonly found in the form of sand. Other elements like sodium, calcium, and magnesium are added to modify its properties. Additionally, trace elements like iron, boron, and aluminum may be included to impart specific characteristics such as color or resistance to heat.
It would be a soft metal with a low melting point.
"Eka boron" and "eka silicon" are placeholder names given to hypothetical elements predicted by Dmitri Mendeleev in his periodic table before their actual discovery. Eka boron is now known as Scandium, while eka silicon is now known as Germanium.
Boron (B), Silicon (Si) and Arsenic (As) are all metalliods.
Silicon on its right , Boron above, and Gallium below it.
The modern name of Eka Boron is Francium. It is a highly radioactive element with the symbol Fr and atomic number 87 in the periodic table.
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.
he predicted the places where he knew elements should be but he couldn't visibly see. Back when Mendeleev was alive, what you could not see you could not measure. This explains why he couldn't see the noble gasses.
germanium
No, boron is in group 13, silicon is in group 14.
None of those elements are nonmetals.The outlier of the group is aluminium, which is usually considered a metal. The other three are all normally though of as being "metalloids".
Gallium was named eka-aluminium by Mendeleev.
