Answer 1

Answer:

option c is your correct answer......

Answer 2

The combination n=3, l=1, ml=-3 (option 3) is not possible.

• 'n' represents the numerical quantum number, 'l' represents the azimuthal quantum number and 'ml' is the magnetic quantum number.
• l can always only have values(subshells) equal to n-1. Also, ml can have 2l+1 orbitals with values only equal to -l, 0, +l.
• In options 1, 2 and 4, all values of n, l and ml are within this limit and hence can exist.

If n=7, l=0,1,2,3,4,5,6 and ml=-6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6 (option 1)

If n=2, l=0,1 and ml=-1,0,+1 (option 2, 4)

• However, in option 3, the value of ml is greater than -l, which is not possible.

If n=3, l=0,1,2 and ml must be=-2,-1,0,+1,+2
