Question

Maximum value (n+1+m) for unpaired electrons in second excited state o

Answer 1

Answer:

The electronic configuration of chlorine (atomic no 17) is

1S2 2S2 2P6 3S2 3P7

max value of principle quantum no is 3

Max value of azimuthal quantum no is 1

Max value of magnetic quantum no is 1

Max value of (n+l+m)=(3+1+1)=5

The valency of this element is 1.It is P block element. It belongs in group 17 in modern periodic table.

Answer 2

Answer:

max value of (n+1+m) =(3+1+1) =5
