Question

each period in the periodic table corresponds to a(n)

orbital

energy sublevel

suborbital

principal energy level

Explanation:

In the periodic table, the period number of an element corresponds to the principal energy level of its outermost electrons. Orbitals are regions within energy levels where electrons are likely to be found. Energy sublevels (like s, p, d, f) are parts of principal energy levels. "Suborbital" is not a standard term in this context. So, based on the structure and electron - configuration principles related to the periodic table, we can determine the answer.

Answer:

principal energy level
