eka-boron(answer)::eka-aluminum​

Answer 1

Answer:

For instance, the predicted element designated as “eka-aluminum,” he located below the known element aluminum. It was later identified as gallium. Gallium, germanium, and scandium were all unknown in 1871, but Mendeleev left spaces for each and predicted their atomic masses and other chemical properties.

Explanation:

Eka-aluminium is gallium (Ga). It lies in group3 of the Mendeleev's periodic table and thus, has a valency or 3. The formula of its chloride is GaCl3.

eka- +‎ boron: the name given by Dmitri Mendeleev to the then undiscovered element at the position of scandium in his periodic table.

.From the name given by Dmitri Mendeleev to gallium prior to its discovery; from the fact that it lies below aluminium in the periodic table. MLA Style. "Eka-aluminium." YourDictionary.
