Select the correct statements about a 4f orbital.

AIt has no radial node.
BIt has three angular nodes.
CThe orbital angular momentum is $12 ℏ$ .
DThe subshell can hold 10 electrons.

Answer: A, B, C

l = 3

: radial

= 4 - 3 - 1 = 0

(A), angular nodes

= 3

(B),

L = 12 ℏ

(C). The f subshell has 7 orbitals and holds 14 electrons, so D is false.
