Mendeleev used the prefix eka- to predict the existence of unknown elements, eka means one in Sanskrit. For example, he predicted the existence of germanium, one element below silicon, which he named eka-silicon. Based on this observation, what would be the identity of the element that Mendeleev named eka-aluminum when he formed the periodic table?
