What are Eka Boron Eka Aluminium and Eka Silicon

Answer: Mendeleev coined the term eka-boron to describe an undiscovered element that is now known as scandium. Scandium is a rare earth metal in the periodic table’s group 3. It has the atomic number 21 and the symbol Sc. It’s a silver metallic whited-block element. Scandium is a silvery-white metal that is fairly soft. It is fairly stable in air, but the development of Sc₂O₃ oxide on the surface causes it to gradually change colour from silvery white to yellowish.

Mendeleev named the unknown element Eka-aluminium, which is now known as Gallium. Gallium belongs to the periodic table’s group 13. It has the atomic number 31 and the symbol Ga. At ordinary temperature and pressure, it’s a soft, silvery metal with a very low melting point. Gallium arsenide has a structure similar to silicon and can be used as a silicon alternative in electronics. It’s a crucial part of a lot of semiconductors.

Mendeleev predicted the presence and properties of several unknown elements, among other things. One of these elements was Germanium, which Mendeleev termed “eka-silicon” on his periodic table, which meant “beyond silicon.” Mendeleev coined the term Eka-silicon to describe an undiscovered element that is now known as Germanium. The periodic table group 14 contains germanium. It’s called metalloid because it contains both metal and non-metal packages. It has the atomic number 32 and the symbol Ge. It’s a brilliant, brittle grey white.

As a result, eka-boron equals scandium, eka-aluminium equals gallium, and eka-silicon equals germanium.
