s - orbital: For s orbital Azimuthal quantum number = 0 and the magnetic quantum number m = 0 hence s orbitals have unique orientation in space. Thus s orbital corresponds to spherical shape with the atomic nucleus at its centre. For every value of 'n', there is one 's' orbital i.e. s orbitals are present in all principal energy levels.
