Verified step by step guidance1
Understand that the periodic table is arranged in periods (rows) and groups (columns). The second period corresponds to the second row of the periodic table.
Recall that the second period contains elements with atomic numbers from 3 to 10, starting with Lithium (Li) and ending with Neon (Ne).
Identify the atomic numbers of the given elements: Aluminum (Al) is 13, Sodium (Na) is 11, Neon (Ne) is 10, and Magnesium (Mg) is 12.
Compare these atomic numbers to the range of the second period (3 to 10). Only elements with atomic numbers within this range belong to the second period.
Conclude that Neon (Ne), with atomic number 10, is the only element listed that is found in the second period of the periodic table.
