Choose an option
Show full solutionCorrect option: C
Correct answer
Cn = 3, l = 2, m = 1, s = +1/ 2
Step-by-step explanation
In which quantum number have highest ( n + l ) value, will represent highest energy of an atom.
In option (C), n + l = 3 + 2 = 5 = maximum.
In option (C), n + l = 3 + 2 = 5 = maximum.
