Unknown titleth element in the table resembles the first), but could go further. Given this repetition rule, he could predict that an element (he named it eka-silicon) will be discovered which will resemble <span>silicon and have an atomic weight of 72. Sure enough it was found in 1886, and was named germanium. Likewise, his prediction of eka-aluminium too came true; gallium discovered in 1875 had all properties predicted by Mendeleev.
