Answer:1 . Azimuthal quantum number 2. Principal quantum number Explanation:The energy of electrons can be determine by following number1 . Azimuthal quantum number .This is denoted by l.2. Principal quantum number .This is denoted by n.If the energy of electrons is high then it means that it have high principal quantum number(n) and If the energy of electrons is low then it means that it have low principal quantum number(n).

Answer:The values of the principal quantum number, n, and the azimuthal quantum number, l, are needed to determine the energy of an electron in a many-electron atom.Explanation:The principal quantum number, n, characterizes the energy and average distance of an orbit or shell from the nucleus. n has values 1,2,3,4… for the K,L,M,N… energy levels respectively. It also helps us to determine the maximum number of electrons in a shell, given by: 2n2 where n = the numerical value of the shell type.The subsidiary or azimuthal quantum number, l, helps us determine how many subshells are in each electron shell and the shape and type of each orbital. Under high resolution magnetic field the principal electronic shells split into closely arranged subshells with slightly different energies.The l values ranges from 0 to (n-1) which is 0,1,2,3 for the s,p,d,f subshells respectively.
