Question

plzz help me guys chemistry class 11​

Answer 1

Answer:

(c) is not possible

Explanation:

(a) when n=3 the values of l can range from 0 to n-1 in this case, n-1=2

therefore, 2 is possible as a value for l

for l=2 the values of ml range from -l to +l = -2,-1,0,1,2

thus,ml= 1 is a possible value

spin can be either negative or positive

thus, (a) is a set of quantum number

using the same method as above.. we can prove (b) and (d) is a quantum number

(c) does not satisfy the conditions hence is not a quantum number

hope this helps
