Metalloids – are found along the zigzag line on the periodic table. The only exception is Aluminum.

Metals are located on the left of the periodic table, and nonmetals are located on the upper right.

The diagonal line at the right side of the table shown below separates the elements into two groups: the metals and the nonmetals. The elements that are on the left of this line tend to be metals, while those to the right tend to be nonmetals. The elements that are directly on the diagonal line are metalloids.

Non-metallic materials are any materials, both synthetic and natural, which do not contain metal. These materials are able to retain their unique chemical properties during the machining process. There are a wide variety of non-metallic materials, including: Rubber.

Most of the non-metals are gasses. In the periodic table, they are represented under Polyatomic non-metal, Diatomic non-metal, Noble gases. carbon, phosphorus, sulfur, selenium, and iodine are the solid non-metals. Non-metals are further classified into the following groups.

Nonmetallic minerals are, for example, sand, gravel, limestone, clay, and marble. Such materials lack metallic characteristics like good electric and thermic conductivity, luster, rigor, and malleability; they are, however, essential for many industries.

Metallic Minerals are minerals in which metal elements are present in their raw form. Non-metallic minerals do not contain any metal substances in them. When metallic minerals are melted a new product is formed. In the case of non-metallic minerals, you don’t get any new product after such a process.

Metallic resources are things like Gold, Silver, Tin, Copper, Lead, Zinc, Iron, Nickel, Chromium, and Aluminum. A mineral resource is a volume of rock enriched in one or more useful materials.

Ores of iron, aluminum, gold, silver are examples of metallic minerals. Diamond, slat, potash etc.

Metallic minerals are classified into two categories: 1) Ferrous minerals: The metallic minerals that contain iron are known as ferrous minerals. In the total production of metallic minerals, 75% is constituted by ferrous metallic minerals. Its common examples include iron ore, manganese, chromite and nickel.
