Question

What are the possible values of $\mathrm{l}$if $\mathrm{n}=5$?

Answer 1

Principal quantum number:

• The principal quantum number $‘\mathrm{n}’$ is a positive integer with a value of $\mathrm{n}=1,2,3.......$.
• “The principal quantum number determines the size and to large extent the energy of the orbital.”

Azimuthal quantum number:

• “It defines the three-dimensional shape of the orbital.”
• For a given value of $\mathrm{n}$, $\mathrm{l}$ can have $\mathrm{n}$ values ranging from $0\mathrm{to}\mathrm{n}–1$.

For $\mathrm{n}=5$, the value of $\mathrm{l}$ranges from $0,1,2,3,\mathrm{and}4$.

Thus, the values of $\mathrm{l}$ if $\mathrm{n}=5$ will be $0,1,2,3,\mathrm{and}4$
