Give the full set of quantum numbers for the electron lost when a Cs atom ionizes.
a. n = 6; l = 1; ml = –1; ms = +½
b. n = 5; l = 0; ml = +1; ms = –½
c. n = 5; l = 0; ml = 0; ms = –½
d. n = 6; l = 0; ml = 0; ms = +½
Is the answer A.
The electron LOST is a free electron. leaving a Cs+ ion with a filled-shell Xenon configuration behind.
n = 5 and l=0 ( a 1S spectroscopic state)
The ground state for the Cs+ ion (not the electron) would be n = 5; l = 0; ml = 0 BUT there would be no net electron spin, and 0 ms
I do not agree with the choices. The problem is poorly and confusingly worded
