Earth Science: Chemistry – Inorganic Chemistry – The Work of Chemists Chemistry has its origins in the world of alchemy. It includes the search for the chemical structure of even the minutest quantities of materials. From nanotechnology to macroscale production, chemists seek new materials and more useful products using both computers and traditional laboratory equipment. … Read more
Earth Science: Chemistry – Inorganic Chemistry – Material in Flux Chemical processes are everywhere. Engines transform gasoline into exhaust gases. Iron chains become rust. In an oven, a raw roast is transformed. In our bodies, our food is transformed into new materials. Industrially, large amounts of new substances are created by controlling chemical reactions. Earth … Read more
Earth Science: Chemistry – Inorganic Chemistry – The Periodic Table A copy of the periodic table hangs in every chemistry classroom around the world. Today it includes 111 confirmed elements, arranged in groups and periods according to their atomic number and properties. Chemists had long speculated about an order for the elements when, in 1829, … Read more
Chemistry – Inorganic chemistry – Matter The ancient Greek philosophers believed that all matter consisted of four elements: fire, water, air, and earth. It was not until modern times that researchers succeeded in identifying the building blocks of matter. Through this they were able to give order to the various materials in the world and … Read more
INORGANIC CHEMISTRY In science and in everyday life, chemistry appears as a world of substances: whether pure materials or mixtures; elements or complex molecules; stable matter or reactive compounds. Chemistry describes a microcosm that is constantly in motion and forming new combinations, whether in the natural environment, industrial lab-oratories, or our own households. Today’s chemists … Read more
