Respuesta :
Each additional energy level contains one more sublevel then the energy level below it.
Therefore the first energy level contains only the s sublevel, the second contains s and p, the third contains s, p, and d, and so on.
Therefore the first energy level contains only the s sublevel, the second contains s and p, the third contains s, p, and d, and so on.
Answer: s sublevel : First energy level
s and p sublevel: Second energy level
s, p, and d sublevel: Third energy level
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, first energy level
n =1, l can have value 0 to (n-1) i.e. 0 only. Thus l can have only one value of zero which corresponds to s sublevel.
2. For n= 2, second energy level
n=2, l can have value 0 to (n-1) i.e. 0 and 1 only. l= 0 corresponds to s sublevel and l= 1 corresponds to p sublevel.
3. For n= 3, third energy level
n=3, l can have value 0 to (n-1) i.e. 0 ,1 and 2 only. l= 0 corresponds to s sublevel , l= 1 corresponds to p sublevel and l= 2 corresponds to d sublevel.
