Verified step by step guidance1
Understand the classification of elements on the periodic table: elements are broadly categorized as metals, nonmetals, and metalloids based on their physical and chemical properties.
Recall that metals are typically found on the left and center of the periodic table and are characterized by properties such as good electrical conductivity, malleability, and luster.
Identify the position of each element in the periodic table: Phosphorus (P), Sulfur (S), and Oxygen (O) are located on the right side of the periodic table and are classified as nonmetals.
Recognize that Sodium (Na) is located in Group 1 (alkali metals) on the far left side of the periodic table, which is a region known for metallic elements.
Conclude that Sodium (Na) is classified as a metal, while Phosphorus, Sulfur, and Oxygen are nonmetals.
