Based on the provided information and understanding of electronic configurations, the 7p orbital has the highest energy level listed.
The order of electron orbital energy levels, starting from the lowest energy to the highest, dictates how electrons fill orbitals in an atom. This order is crucial for understanding chemical properties and bonding. The reference material provides a sequence, and identifying the last entry in that sequence answers the question.
The sequence provided is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p.
It is important to note that this order is a general guideline and can sometimes be altered based on specific atoms and their interactions. However, for the vast majority of elements and based upon the data provided, the 7p orbital is indeed the orbital with the highest energy from the list.
