Non Metals A non metal is a material which do not have properties of metals like lustre They are non malleable, non ductile, non sonorous and bad conductor of heat and electricity Example- Carbon, Sulphur, Phosphorous. Metals Non-metals; Appearance: Shiny: Dull: State at room temperature: Solid (except mercury, which is a liquid) About half are solids, about half are gases, and one (bromine) is a liquid: Density Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.These metals have properties that you normally associate with the metals you encounter in everyday life: 1. 7)They have low melting and boiling point. For e.g. Notice that metals and non-metals have opposite properties to each other. These compounds have some of the same characteristics as the elementals forms: usually they melt or boil at relatively low temperature and don't conduct heat or electricity. They are electronegative in character. The characteristic feature of metals like copper and aluminium is a high electrical and thermal conductivity, while nonmetals such as phosphorus metal and sulfur are insulators.
Non-metals can react with each other to form compounds in which electrons are shared. Also, many periodic tables have a stair-step line on the table identifying the element groups. Nonmetals, when reacting with metals, tend to gain electrons (typically They are electronegative in character. Characteristics of Non-metals.
The characteristic properties of metals and nonmetals are quite distinct, as shown in the table below. Metals form oxides that are basic, but non-metals form oxides that are acidic. The metalloids separate the metals and nonmetals on a periodic table. The line begins at boron (B) and extends down to polonium (Po). For e.g. For example, sulfur and carbon are both non-metals. It is usually easy to tell metals and non-metals apart, but some tests are more reliable than others. Finally, most metal elements lose electrons during reactions. The physical properties make them useful for many purposes. While nonmetals may have an allotrope that appears metallic, all of the allotropes of metals look like what we think of as a metal (lustrous, shiny). 6)They are solids, liquid and gases at room temperature. Sodium Chloride (NaCl) 3. There is one non-metal element that can sometimes act as a metal. Metals form oxides that are basic, but non-metals form oxides that are acidic. Metals conduct heat well because they can absorb a lot of kinetic energy without breaking their bonds. 3)They are bad conductor of heat and electricity.
Metals are a good conductor of electricity which means that they can conduct electricity due to the free moving electrons present in them. Non-metals have a tendency to gain or share electrons with other atoms. For example, graphite and diamond are two allotropes of the nonmetal carbon, while ferrite and austenite are two allotropes of iron.
Nonmetals tend to have full orbitals, so electrons do not …
