what are metals and non metals?

In chemistry, a nonmetal chemical element that generally lacks many metal components; they vary from colorless gases to glossy and soluble solvents. The electrons in the nonmetals behave differently from those in the metal

Elements can be classified as metals or nonmetals based on their properties. Most of the time, you can say that the element is metal in terms of its metallic gloss, but this is not the only difference between these two common groups of elements.

Important Excerpts: Differences between Metals and Non-Metals

The periodic table contains metal elements, non-metals, and elements with structural elements between two groups (metalloids).

Metals are usually solid, metal-like materials, with high electrical temperatures and thermal conductivity as well as high melting and boiling points.

Nonmetals are usually soft, usually colored elements. It may be solid objects, liquids, or gases. They have lower points of melting and boiling than most metals and are usually not good conductors.

Instruments

Many elements are metal. These include alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. In the periodic table, metals are separated from nonmetals by a zig-zag line passing through carbon, phosphorus, selenium, iodine, and radon. These elements and those to the right of them are stainless steel. The elements on the left of the line may be called metalloids or semimetals and have intermediate spaces between metal and non-metallic. Physical and chemical properties of metal and non-metallic materials can be used to differentiate.

Steel Properties:

1. Shiny (shiny)
2. Good heat and electric conductors
3. High melting point
4. High density (heavy in size)
5. Soft (unbeatable)
6. Ductile (can be pulled on ropes)
7. It tends to harden at room temperature (the exception is mercury)
8. Opaque as a thin sheet (cannot see through metal)
9. The instruments are sonorous or make a sound like metal when struck

Metal Chemical Properties:

1. Have 1-3 electrons in the outer shell of each metal atom and easily lose electrons
2. Easy corrosion (e.g., damaged by oxidation such as rust or rust)
3. Get rid of electrons easily
4. Forms basic oxides
5. Have low electronegativity
6. Good mitigation agents
7. Iron: brass (left); metalloid: arsenic (center); and non-metallic: sulfur (right).

Nonmetals

Nonmetals, with the exception of hydrogen, are found to the right of the periodic table. Non-metallic elements are hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, selenium, all halogen, and noble gases.

Non-Metallic Material:

1. Shiny (blurred appearance)
2. Poor conductors of heat and electricity
3. Noductile solids
4. Strong solid
5. It may be solid, liquid or gases at room temperature
6. Light as a thin sheet
7. Nonmetals are not sonorous
8. Nonmetal Chemical Properties:
9. It usually has 4-8 electrons in its outer shell
10. Easily find or share electron valence electrons
11. Forms acidic oxides
12. Have high electronegativity
13. Good oxidizing agents

Both metals and nonmetals take different forms (allotropes), with different shapes and properties to each other. For example, graphite and diamond are two carbon nonmetal allotropes, while ferrite and austenite are two allotrope metals. While nonmetals may have allotrope that looks like metal, all metal allotropes look like what we think of as metal (glossy, glossy).

Metalloids

The distinction between metals and non-metals is unclear. Materials with both metal and non-metallic structures are called semimetals or metalloids. The steps of the stairs almost separated the irons from the non-stones in the periodic table. However, pharmacists recognize that naming one element "metal" and next to it "metalloid" is a judgment call. In fact, most metals show the characteristics of nonmetals under certain conditions, and nonmetals act as a metal in some cases.

Hydrogen is a good example of an element that acts as a nonmetal at times, but as a metal at times. Under normal circumstances, hydrogen is a gas. Therefore, it acts as a nonmetal. However, under high pressure it becomes a solid metal. Even like gas, hydrogen usually forms a +1 (metal point). However, it sometimes makes -1 anion (non-metallic material).
