Final answer:
The angular momentum quantum number defines the shape of an orbital.
The answer is option ⇒c
Step-by-step explanation:
The angular momentum quantum number, or l, defines the shape of an orbital. It describes the general region an electron occupies in the atom. The value of l depends on the principal quantum number, n. For example, if n = 2, l can be either 0 or 1.
The magnetic quantum number, or m, specifies the relative spatial orientation of a particular orbital. It determines the number and arrangement of orbitals within a subshell.
The spin quantum number, or s, is associated with the electron's intrinsic spin angular momentum. It indicates the orientation of the electron's spin along the z-axis.
The answer is option ⇒c. angular momentum
