Verified step by step guidance1
Understand that the periodic table is divided into several categories based on the properties of elements: metals, nonmetals, metalloids, and noble gases.
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.
Recognize that nonmetals are located on the right side of the periodic table and generally have properties opposite to metals, such as poor conductivity and brittleness.
Note that metalloids have properties intermediate between metals and nonmetals and are found along the zig-zag line separating metals and nonmetals.
Identify that noble gases are a small group of inert gases located in Group 18 and represent only a small fraction of the elements.
