<P> In atomic physics , the magnetic quantum number , designated by the letter m , is the third in a set of four quantum numbers ( the principal quantum number , the azimuthal quantum number , the magnetic quantum number , and the spin quantum number ) which describe the unique quantum state of an electron . The magnetic quantum number distinguishes the orbitals available within a subshell , and is used to calculate the azimuthal component of the orientation of orbital in space . Electrons in a particular subshell ( such as s , p , d , or f ) are defined by values of l ( 0 , 1 , 2 , or 3 ) . The value of m can range from - l to + l , inclusive of zero . Thus the s , p , d , and f subshells contain 1 , 3 , 5 , and 7 orbitals each , with values of m within the ranges 0 , ± 1 , ± 2 , ± 3 respectively . Each of these orbitals can accommodate up to two electrons ( with opposite spins ) , forming the basis of the periodic table . </P>
