Which elements did Mendeleev leave gaps for in his periodic table and what names did he give them?

(N/A) Mendeleev predicted the existence of several elements that were not discovered at that time. He left gaps in his periodic table for these elements and named them by prefixing the word '$eka-$' (Sanskrit for 'one') to the name of the element immediately preceding them in the same group.

$Element$	$Mendeleev's$ $Name$
