D

Verified step by step guidance1
Understand that the periodic table classifies elements into several broad categories based on their properties: metals, nonmetals, metalloids, and noble gases (which are a subset of nonmetals).
Recall that metals are generally 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 typically have properties opposite to metals, such as poor conductivity and brittleness.
Know that metalloids have properties intermediate between metals and nonmetals and are found along the zig-zag line dividing metals and nonmetals.
Since the question asks which type most elements are classified as, remember that the majority of elements in the periodic table are metals, making metals the correct classification for most elements.
