f- orbital

So on the periodic table, the s-, p-, and d- orbitals all correspond with a block of the periodic table. But I've noticed that some random elements use the f- orbital and I can't seem to figure out what the telltale sign is that they do. What block/part of the periodic table corresponds to the f- orbital?

The last two rows of the periodic table consist of the f-orbitals. By looking at the atomic number of those elements, you can see that they fit in the middle of the periodic table. It is the row after Xe

Observe the atom numbers of the elements in the f block,notice where they fit in with the rest of the table, everything with atomic numbers above 58 will have electrons in the f block.

The f-orbital consists of the two rows that are outside the periodic table that start at atomic # 57-71 and 89-103.
