Some are in the lanthanide series, some are transition metals, amd some are in the actinide series. The groups are the same as the elements above them. You can see which is which here:

As a bio-chem undergrad. i detect that i did no longer memorize the 1st 2 rows the table on purpose. Memorization of the 1st 2 rows come from doing homework issues returned and returned returned. by using the time you get via introductory and everyday chemistry, you will a minimum of comprehend the atomic variety and mass of H, N, C, and O in the decrease back of your head. in all probability even some different aspects alongside with Cl, Fl, B, S, I, Na, Li, Fe..and so on.. yet a number of my instructors has pronounced, aside from some regularly used aspects, something of the periodic table could want for use as strategies, no longer memorized.

The bottom row of elements are Actinides.
