Answer: Scandium
Explanation:
Mendeleev noted some gaps in the periodic table for which he predicted three elements Eka Boron, Eka Silicon, and Eka Aluminium which was subsequently named Scandium, Germanium, and Gallium respectively.
The unknown predicted element had properties similar to the later known elements.
Eka Boron was predicted to have an atomic mass of 44, while Scandium had an atomic mass of 44.955.
Eka Boron was subsequently named as Scandium by Mendeleev.
