Question

Complete the table below by filling in the principal quantum number n and angular momentum quantum number l for each electron subshell listed.
subshell principal quantum number n angular momentum quantum number l
4f
7s
4p
7p

Answer 1

Answer:

For 4f  the principal quantum number, n is 4 and the angular momentum quantum number l is 3

7s: n = 7 and l = 0

4p: n = 4 and l = 1

7p: n = 7 and l = 1

Explanation:

The principal quantum number gives the energy level of the electron in an atom. It shows the shells in which an electron is in an atom.

if n = 1, 2, 3, 4...; it corresponds to K, L, M, N... shells in an atom

The numerical coefficient of the subshell gives the pricipal quantum number.

for instance in 4f, the principal quantum number, n is 4  because 4 is the coefficient.

The angular momentum quantum number, l gives the energy sublevel or subshell.

Angular momentum quantum number has integral values, l = 0, 1, 2, 3... which correspond to  s, p, d, f,..  orbitals.

Thus for 4f  the principal quantum number, n is 4 and the angular momentum quantum number l is 3

similarly, for 7s: n = 7 and l = 0

4p: n = 4 and l = 1

7p: n = 7 and l = 0
