Question

For an $4p_y$ orbital, there are nodal plane ....and azimuthal quantum number l....

• A. 1,0
• B. 0,1
• C. 1,1
• D. 2,1

Answer 1

Answer: (C)

(c) 1,1

Answer 2

For an atomic orbital, the number of nodal planes (angular nodes) is equal to its azimuthal quantum number, $l$. For any p orbital, the azimuthal quantum number is $l=1$. Therefore, a $4p_y$ orbital has 1 nodal plane and its azimuthal quantum number is $l=1$.
