Electrons in the electron cloud of an atom are located at specific energy levels. We cannot say with certainty exactly where the electron is physically located at any given moment, and that's because electrons can be at different physical locations at any instant of time. There are quantum mechanical reasons for this, and just one example of the "variability" of location of an electron is quantum mechanical tunnelling.
The exact location of an electron can not be known. Electrons' locations can be merely estimated. Electron "clouds" or orbitals are general areas where an electron is likely to be found. There is always uncertainty as to where the electron actually is.
it really depends i know for sure that its 3 electron clouds
Fermium has seven electron shells.
in the electron clouds of an atom
No, there really aren't any pictures of the electron cloud of an aluminum atom. Atoms are too small for conventional pictures. There are drawings of the electron clouds of atoms, but they're just "fuzzy shapes" because the location, or, rather, the probable location, of electrons cannot be precisely stated. It can only be given as a probability density function - an "indefinite area where an electron is most likely to be" as it is hanging around in orbit. The shapes of the electron clouds vary as we look at them from atom to atom. A link is provided to a post introducing the viewer to the basic shapes.
They are the probability of finding the electrons.

Electrons are found in the shells and clouds.
It has 11 electrons total. These are in 3 shells.
The correct number of electron clouds or shells sodium has is 3.
