What are examples of metals nonmetals and metalloids?
The seven metalloids are boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. The three types of elements occupy their own places in the Periodic Table. Metals are at the left, nonmetals are at the right, and metalloids straddle a zig-zag line that separates metals from nonmetals.
- Marble, granite, sandstone, porphyry, basalt, other ornamental or building stone (excluding slate);
- Chalk and dolomite;
- Limestone and gypsum;
- Chemical and fertilizer minerals;
- Clays and kaolin;
- Sand and gravel; and.
- (2) Special non-metallic minerals, such as diamond, crystal, Iceland spar, mica, tourmaline, etc; (3) chemical non-metallic minerals, such as phosphorus, sulfur, potassium, magnesium, trona, Glauber's salt, ceresin; Non-metallic mineral is mined easily and largely.
- The metal ores itself can be considered as a mineral. Some common metal minerals include Iron, Copper, Gold, Silver, etc. Non-Metallic Minerals do not contain metal elements in their inorganic chemical formula. Some common examples include; Clay, Diamond, Dolomite, Gypsum, Mica, Amethyst and Quartz, etc.
- Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Calcite and aragonite are non-metallic minerals because they have no lustre. Limestone is not a mineral. its very common to find traces of iron or manganese in a limestone .
Nonmetals are located on the far right side of the periodic table, except hydrogen, which is located in the top left corner. The 17 nonmetal elements are: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.
- Metals give electrons, while nonmetals tend to take electrons. Pure metals tend to have a shine or luster, but nonmetals tend to be dull in appearance. They tend to have relatively high densities. They also tend to be malleable and ductile, which means that they can be hammered and drawn into wires.

The 17 nonmetal elements are: hydrogen, helium, carbon, nitrogen, oxygen, fluorine, neon, phosphorus, sulfur, chlorine, argon, selenium, bromine, krypton, iodine, xenon, and radon.
- The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal.
Non-metals are not able to conduct electricity or heat very well. As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The non-metals exist in two of the three states of matter at room temperature: gases (such as oxygen) and solids (such as carbon).
- Carbon is a solid non-metal element. Pure carbon can exist in two very different forms - diamond and graphite. The table shows some differences between them. Diamond is the hardest natural substance on Earth, but it is also very brittle and will shatter if hit with a hammer.
- Sulfur or sulphur is a chemical element with symbol S and atomic number 16. It is an abundant, multivalent NON METAL. Under normal conditions, sulfur atoms form cyclic octatomic molecules with chemical formula S8.
- Sodium is an element that is a member of the alkali metal group with a symbol Na. It is physically silver colored and is a soft metal of low density. Pure sodium is not found naturally on earth because it is a highly reactive metal.
