Verified step by step guidance1
Understand that the periodic table classifies elements into broad categories based on their properties: metals, nonmetals, and metalloids.
Recall that metals are elements that typically have high electrical and thermal conductivity, are malleable and ductile, and tend to lose electrons in chemical reactions.
Recognize that most elements on the periodic table fall into the category of metals, which are located primarily on the left and center of the table.
Note that metalloids have properties intermediate between metals and nonmetals and are found along the zig-zag line dividing metals and nonmetals.
Remember that noble gases are a small group of nonreactive gases located in Group 18, and nonmetals are found on the right side of the table but are fewer in number compared to metals.
