Properties of non-metals are usually the opposite of properties of metals Non-metals can be solid, liquid, or gas at room temperature depending upon the element. Non-Malleable and Ductile: Non-metals are very brittle, and cannot be rolled into wires or pounded into sheets. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals. Metals. ... Graphite, the standard state of carbon, has a lustrous appearance and is a fairly good electrical conductor. alkali metals, alkaline earth metals, d-block transition metals, lanthanides, actinides, etc. The metals like Sodium ( Na) and Potassium ( K ) are easily cut with the help of a knife. malleable and ductile. Key Differences Between Metals, Non-Metals, and Metalloids. Solid Solutions: They can form alloys with other metals. Metals are the elements which exhibit the highest degree of metallic behavior is known as metals, on the contrary Non-metals are such elements which do not possess any metallic behavior, and Metalloids are those elements, that possess some of the properties like metal, while some like non-metal.
