The iron group contains iron Fe and nickel Ni. These metals possess a body-centered cubic structure. Nickel and iron are mutually soluble because their atomic radii are both equal to 1.24 angstrom. This solid solution is frequently found in meteorites and probably constitutes much of the earths core.
Physical properties of iron element. pure iron is known to be a soft metal, with a silver white or grayish color. some of its most important properties are ductility, malleability and thermal conductivity. malleability lets iron be beaten into sheets, without cleavage and ductility makes it possible for thin wires to be drawn from it.

Iron metal extracted from iron ore. it never exists in pure form and has to be extracted from iron ore by eliminating the impurities. gold is the oldest and most precious element to be known. manganese ore is a silvery brittle or grey-white metallic ore occurs in many forms and found worldwide.
Pyrite and coal mining. sulfur occurs in coal in three different forms 1 organic sulfur, 2 sulfate minerals, and 3 sulfide minerals mostly pyrite with minor amounts of marcasite. when the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions.
Materials science identification exercise. in this activity, you will check your knowledge of the material classification in materials science, as presented in the lesson.
Coal types geologists also classify coal types according to the organic debris, called macerals, from which the coal is formed. macerals microscopic organic constituents found in coal are identified microscopically by reflected light - the reflective or translucent properties of the coal indicating the individual component macerals
Jun 16, 2018nbsp018332if you think about the various observable properties of matter, it will become apparent that these fall into two classes. some properties, such as mass and volume, depend on the quantity of matter in the sample we are studying. clearly, these properties, as important as they may be, cannot by themselves be used to characterize a kind of matter to say that water has a mass of 2 kg is ...
