Answer: first energy level : s sublevel
second energy level : s and p sublevels
third energy level : s, p and d sublevels
Explanation:
Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....
Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
1. For n= 1 i.e. first energy level
l can have value 0 to (n-1) i.e. 0 only. For l= 0, the sublevel is s.
2. For n= 2 i.e. second energy level
l can have value 0 to (n-1) i.e. 0 and 1 only. For l= 0, the sublevel is s and l=1 , the sublevel is p.
3. For n= 3 i.e. third energy level
l can have value 0 to (n-1) i.e. 0, 1 and 2 only. For l= 0, the sublevel is s and l=1 , the sublevel is p and l=2, the sublevel is d.
