    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.

    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.
