Do scientists know how many electrons an element has? Can someone explain why I was taught about shells of electrons in atoms?

Yes, we know how many electrons each element has. It is stated on the periodic table.
Two electrons, by their nature, cannot be in the exact same quantum state. For that reason, they arrange themselves into shells in an atom. These shells are solutions to the Schrodinger equation (the basic equation of nonrelativistic QM).
