Answer:
Every period in the periodic table ends with a noble gase.
Explanation:
Period in the periodic table is the row of elements.
Elements in a row have the same number of electron shells. Each period represents the consecutive occupation of orbitals in an atom's valence shell, with the long periods representing the occupation of orbitals in a d subshell.
Every period in the periodic table ends with noble gases. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).
