                             Significance- This gives the number of orientations of a subshell.

                     Spin quantum number(s) :
                            This quantum number gives the net spin of an electron.

                            In an orbital 2 electrons are present with opposite spin.
                            The value of s is +1/2  and -1/2.

                            Angular momentum of an electron is an orbital according to spin,
