Question

question 5 (1 point)
each period in the periodic table corresponds to a(n) ____.
○ a principal energy level
○ b suborbital
○ c energy sublevel
○ d orbital

Explanation:

The periodic table's periods are related to electron configuration. Each period number corresponds to the principal energy level (\(n\)) that electrons are filling. For example, elements in period 1 have electrons in the \(n = 1\) principal energy level, those in period 2 have electrons in \(n=2\) (along with \(n = 1\) already filled), and so on. Sub - orbitals (like \(s\), \(p\), \(d\), \(f\)) are part of sub - levels within a principal energy level. Energy sublevels (e.g., \(2s\), \(2p\)) are within a principal energy level. Orbitals (e.g., a single \(s\) orbital, three \(p\) orbitals) are within sublevels.

Answer:

A. principal energy level
