Question

Total number of radial nodes and angular nodes present in 7p orbitals are:

• A. 5 and 0
• B. 6 and 1
• C. 5 and 1
• D. 7 and 1

Answer 1

The correct option is C 5 and 1

Total number of radial nodes = $n-l-1$
where n = shell number
$l$ = azimuthal quantum number
Total number of nodes = 7 - 1 - 1 = 5
Total number of angular nodes = $l$
So, total angular nodes = 1
