metals and their properties pdf

METALS AND THEIR ORES. Think of some uses of metals and non-metals in your daily life. Metals are generally not used in their pure state but as mixtures of metals or metal and non metal constituents commonly referred to as alloys. n Think of some uses of metals and non-metals in your daily life. Properties of Metals. Ernest Merian passed away in 1995 at the age of 75 while traveling to … We are sometimes interested in their conductivity (thermal, electrical) and magnetic properties. Considering the properties of non-metals it is not shiny, malleable or ductile nor are they good conductors of electricity. Metals are lustrous, malleable, ductile, good conductors of heat and electricity. 2.4 Physical Properties of Metals The physical properties of the metals include luster, colour, size and shape, density, electric and thermal conductivity, and melting point. The worksheet is available as a free download in PDF format. Their physical and chemical properties vary widely. are common elements. The following table shows the important physical properties of some pure metals. edition titled Metals and Their Compounds in the Environment followed relatively quickly in 1991. The metals consist of the alkali metals, alkaline earths, transition metals, lanthanides, and actinides. •When a metal is hammered into a sheet or drawn into a wire, it does not break because the ions are in layers that slide past one another without losing their attraction to the electron cloud. It also has a section to list the physical characteristics of each type of element. Metals are defined as those elements which have characteristic chemical and physical properties. Metals in general have high electrical conductivity, high thermal conductivity, and high density . This worksheet can be used to test students by having them identify elements as metals, nonmetals, or metalloids. their capacity for plastic deformation. relatively high strength, excellent electrical and corrosion properties BUT expensive; applications: jet aircraft landing gear bearing, surgical and dental instruments. n What properties did you think of while categorising elements as metals or non-metals? The familiar types of metals are (iron, aluminium, copper, lead, zinc, silver, gold, etc.) The metals share several common properties, including: What properties did you think of while categorising elements as metals or non-metals? These properties of non-metals provide one means by which we can distinguish metals from non-metals. In some places, the mineral deposits in rock contain a high concentration of one metal. of the properties of metals. These metal deposits are called ores. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature (Gallium is liquid on hot days). Mechanical properties of metals include ductility, i.e. Metals and Non-metals CHAPTER3 In Class IX you have learnt about various elements.You have seen that elements can be classified as metals or non-metals on the basis of their properties. Physical Properties of Metals. physical and mechanical properties of the material in the following articles. They are grouped together in the middle to the left-hand side of the periodic table. Most elements can be considered metals. Metals and Non-metals CHAPTER3 I n Class IX you have learnt about various elements.
