Question
Find the correlation:
Eka boron : Scandium : : Eka Aluminum : ______
Advertisements
Solution
Eka boron : Scandium : : Eka Aluminum : Gallium
Explanation:
Mendeleev used the Sanskrit prefix “eka-” to name elements that he predicted would fill gaps in his periodic table. He named the element to be discovered below aluminium as Eka-aluminium, which was later identified as gallium when it was discovered. Similarly, Eka-boron was later named Scandium, and Eka-silicon was later named Germanium.
