What is the letter code for a subshell with (a) ℓ = 1 (b) ℓ = 3?

The sub-shell having the letter code  ℓ = 1 is the p sub-shell. The sub-shell having the letter code  ℓ = 3 is the f sub-shell.

The lines obtained from spectroscopy are used to useful in naming sub-shells. These are sharp, principal, diffuse and fundamental (s, p, d, f).

These correspond to numeric codes as follows;

ℓ =  0 ( s sub-shell)

ℓ = 1 ( p sub-shell)

ℓ = 2 (d sub-shell)

ℓ = 3 (f- sub-shell)

Hence, he sub-shell having the letter code  ℓ = 1 is the p sub-shell. The sub-shell having the letter code  ℓ = 3 is the f sub-shell.

Explanation:

The shape and letter code of an electron subshell depends on , the angular momentum quantum number.

The range of possible values that could take depends on , the principal quantum number (which gives the main energy level of an electron in an atom.) . However, the letter code that corresponds to each is the same regardless of the principal quantum number. corresponds to the letter "".
