Physical State: Most of the non-metals exist in two of the three states of matter at room temperature: gases (oxygen) and solids (carbon). Non-Malleable and Ductile : Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets.

The most stable tellurium compounds are the tellurides—salts of Te 2− formed with active metals and lanthanides—and compounds with oxygen, fluorine, and chlorine, in which tellurium normally exhibits an oxidation state 2+ or 4+.
9 sie 2021 · Hydrogen has properties of a nonmetal at normal temperatures and pressures and an alkali metal under extremely high pressure. Some periodic tables include a zig-zag line to distinguish between metals and metalloids.
In silicon dioxide, each silicon atom links to four oxygen atoms by single bonds directed toward the corners of a regular tetrahedron, and SiO 4 tetrahedra share oxygen atoms. This arrangement gives a three dimensional, continuous, silicon-oxygen network.
In this explainer, we will learn how to describe, compare, and explain the physical and chemical properties of metals, nonmetals, and metalloids.
The Periodic Table | Chemistry for Majors. Learning Outcomes. State the periodic law and explain the organization of elements in the periodic table. Predict the general properties of elements based on their location within the periodic table. Identify metals, nonmetals, and metalloids by their properties and/or location on the periodic table.
