JEE MAIN - Chemistry (2007 - No. 36)
Which of the following sets of quantum numbers represents the highest energy of an atom?
n = 3, l = 0, m = 0, s = +1/ 2
n = 3, l = 1, m = 1, s = +1/ 2
n = 3, l = 2, m = 1, s = +1/ 2
n = 4, l = 0, m = 0, s = +1/ 2
Обяснение
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.
