What are three types of categories found in the periodic table?
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
Do metalloids have characteristics of both metals and nonmetals?
Yes, metalloids used in electronics are called semiconductors.
What does staircase in periodic table indicate?
It is the dividing line between the elements considered to be metals and the ones considered to be non metals. Sometimes the elements along the line are referred to as metalloids
What are properties of mettalloids?
their properties are in the middle of metals and nonmetals. they are semi conductive, semi metallic, semi malleable, semi ductile, and some give up electrons while some take electrons.
What are two ways metals and nonmetals are different?
Elements may be classified as either metals or nonmetals, based on their properties.Here's a look at the differences between the metals and nonmetals.Most elements are metals. On the periodic table, metals are separated from nonmetals by a zig-zag line stepping through carbon, phosphorus, selenium, iodine and radon. These elements and those to the right of them are nonmetals. Elements just to the left of the line may be termed metalloids or semimetals and have properties intermediate between those of the metals and nonmetals. The physical and chemical properties of the metals and nonmetals may be used to tell them apart.Metal Physical Propertieslustrous (shiny)good conductors of heat and electricityhigh melting pointhigh density (heavy for their size)malleable (can be hammered)ductile (can be drawn into wires)usually solid at room temperature (an exception is mercury)opaque as a thin sheet (can't see through metals)metals are sonorous or make a bell-like sound when struckMetal Chemical Propertieshave 1-3 electrons in the outer shell of each metal atomcorrode easily (e.g., damaged by oxidation such as tarnish or rust)lose electrons easilyform oxides that are basichave lower electronegativitiesare good reducing agentsNonmetalsNonmetal Physical Propertiesnot lustrous (dull appearance)poor conductors of heat and electricitynonductile solidsbrittle solidsmay be solids, liquids or gases at room temperaturetransparent as a thin sheetnonmetals are not sonorousNonmetal Chemical Propertiesusually have 4-8 electrons in their outer shellreadily gain or share valence electronsform oxides that are acidichave higher electronegativitiesare good oxidizing agents
How are metals used in chemistry?
Metals are used in chemistry for coating of some metalloids and nonmetals
What are the metals and nonmetals used in buses?
large-size steel
What are uses of nonmetals?
Non metals are used as insulators (poor conductors)
What are three types of categories found in the periodic table?
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
What metal and nonmetal used in transportation?
Most metals are used somewhere in transportation. The same is the case for nonmetals.
Do metals or nonmetals tend to gain electrons more easily?
nonmetals are located in the right side of the periodic table. The Ionization energy(the amount of energy used to remove an electron) tends to increase from left to right across a period.It is difficult to remove the electrons from the right side because they are becoming stable
Do metalloids have characteristics of both metals and nonmetals?
Yes, metalloids used in electronics are called semiconductors.
What are physical properties used to identify nonmetal?
The properties of nonmetals also tend to vary more from and element to element than do the properties of the metals
Do non metals contuct heat?
Non metals do not conduct heat. They have high resistance.They are insulators.Non metals do not have a pool of 'free electrons' (as metals do with metallic bonds). Hence they generally are poor conductors of heat. Nonmetals such as Styrofoam are widely used as insulators. Graphite is an exception as it is a good conductor of heat with its free electrons.Most of the non metals does not conductors because the do not have free electrons. But graphite is a good conductor. Most of the non metals are insulators.
Are there any materials other than non metals and metals?
Materials can be classified simply as metals and nonmetals. There are other subdivisions also used. These would include:MetalsCeramics and GlassesPolymersCompositesComposites can be further split intoPolymer matrix compositesMetal matrix compositesCeramic matrix composites
