Drag each tile to the correct box.

Match each set of energy sublevels to the principal energy level that contains them.

S sublevel

s and p sublevels

S, P, and d sublevels

third energy level

first energy level

second energy level

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.
