Question

13. Electrons will first enter into the set of quantum numbers n=5,1= 0 or n=3.1=2
a n=5,1= 0
b Both possible
cn=3.1= 2
Data insufficient​

Answer 1

Answer:

(c) is correct option

Explanation:

When n= 5, l = 0

it indicates 5s - orbital

When n= 3, l = 2

it indicates 3d - orbital

So, an electron will first enter into 3d- orbital
