According to the Bohr model, electron's travel through circular orbits. However according to the electron cloud model, where are the electrons located? *
A:Electrons are located in nucleus

B:Electrons are located in variously shaped orbitals (s, p,d, f) and form a "cloud" around the nucleus

C:Electrons are located in solidly shaped orbitals (s, pdf) These are solid structures
inside the atom.

D:Electrons travel randomly all over the atom.
