Metal, Non-metals and Metalloids
Most elements are metals. 88 elements to the left of the stairstep line are metals or metal-like elements.
Nonmetals are found to the right of the stairstep line. Their characteristics are opposite those of metals.
Metalloids are elements on both sides of the zigzag line. They have properties of both metals and nonmetals.
