Determine which sets of quantum numbers are possible and which are impossible by identifying them as true (possible) and false (impossible).

True False  (12,7,-6,0)


True False  (10,9,6,0)

True False  (18,1,-2,-½)

True False  (17,2,5,-½)

True False  (18,5,5,½)

Expert Solution

answers :

True   (12,7,-6,0)

True (10,9,6,0)

False  (18,1,-2,-½)

False  (17,2,5,-½)

True   (18,5,5,½)

explanation:

order of quantum numbers = (n , l , ml, ms )

points to remember :

1) n always greater than l and ml

2) ml should not be more than l . and ml values : ml = - l to +l

so false statements are : 18,1,-2,-1/2

   here l = 1 so ml should be -1,0 ,+1 only not possible for -2

for (17,2,5,-½)   ml values should be -2,-1,0 , +1,+2 but not 5
