Is fulcrum number nine in the periodic table?
There is no element with the name "fulcrum" on the periodic table. Elements on the periodic table are represented by their atomic number and chemical symbol. You may be thinking of an element that is near atomic number nine, which is fluorine (symbol F).
Is manganese a representative element?
Manganese is not a rare earth element. The rare earths range from Lanthanum (atomic number 57) to Hafnium (70) and Actinium (89) to Rutherfordium (102). Manganese is atomic number 25. Looking at the periodic table, you will see two rows at the bottom named Lanthanoids and Actinoids - those are the rare earths.

What are the empty spaces in the periodic table meant for?
It was recognized by the inventor of the Periodic table that these empty spaces are for elements/isotopes that would be discovered someday. Dmitri Mendeleev is generally credited with the publication, in 1869, of the first widely recognized periodic table. He developed his table to illustrate periodic trends in the properties of the then-known elements. Mendeleev also predicted some properties of then-unknown elements that would be expected to fill gaps in this table.
