Question
A certain orbital has no angular nodes and two radial nodes. The orbital is :
Choose an option
Show full solutionCorrect option: B
Correct answer
B3s
Step-by-step explanation
Angular nodes = = 0
Radial nodes (n – – 1) = 2
n – 0 – 1 = 2
n = 3
So orbital is 3s.
Radial nodes (n – – 1) = 2
n – 0 – 1 = 2
n = 3
So orbital is 3s.
