Final answer:
The electron sublevels are listed in order of increasing energy as follows: 4p<5s<4d<5p<6s, which corresponds to option C. This order is consistent with the Aufbau principle and known electron configuration sequences.Therefore, the correct option is: C.4p<5s<4d<5p<6s.
Step-by-step explanation:
The question asks which of the following lists electron sublevels in order of increasing energy: A.4p=4d<5s=5p<6s B.4p<4d<5s<5p<6s C.4p<5s<4d<5p<6s D.6s<5p<4d<5s<4p E.6s<5p<5s<4d<4p.
The correct order in which electron sublevels fill based on their increasing energy is given by the Aufbau principle. Due to this principle, electrons fill atomic orbitals of the lowest available energy first before filling higher energy levels. The general order for filling subshells is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, and so on.
The 4s sublevel is filled before the 3d, and after the 3p. After the 4s sublevel comes the 3d, then 4p, followed by 5s and 4d. Thus, the correct list in increasing energy is: 4p<5s<4d<5p<6s.
Therefore, the correct option is: C.4p<5s<4d<5p<6s.
