In the electron configuration "4p^3", what do the following represent: 4,p, and 3

4p3 means -----------
4= n = number of orbit i,e 4th orbit[ principal quantum number is 4]
p = l = 1i.e. value of azemuthal quantum number is 1i.e p is orbital
3 = number of electrons i.e there are 3 electrons in the p orbital of 4th orbit.
