Magnetic quantum number is represented by m, explains the magnetic properties of the electron. the magnetic field created created by the charged electron can interact with the external magnetic field, due to which the electrons in a given energy subshell ,orient themselves in certain specific regions of space around the nucleus called o rbitals.
the o rbitals of a given subshell are degenerate.
the number allowed to m depends on the l values and ranges from -l through 0 to +l making a total of (2l+1) values. I.e. when l=0,m=0(subshell is s) ,when l=1 ,m=-1,0,+1 (subshell p, which is oriented in three directions x,y,z in space). that is to say p has three degenerate o rbitals oxygen,py,ozone arranged in space along x,y,z axis.
when l=2,m=-2,-1,0,+1,+2 (subshell is d ,which implies that it has five space orientations due to five m values and are designated as day,dxy,dyz,dx^2-y^2 and dz^2).
when l=3,m=-3,-2,-1,0,+1,+2,+3 (subshell is f having orientation in seven different directions in space).
