Water contamination is a major environmental problem in many cities of the world. Most water contamination results from industry and human activities that generate toxic substances (e.g., metals). Rheophilic and aquatic mosses are found in lotic ecosystems, and their morphological and physiological traits are responsive to ecological and pollution gradients. Here we hypothesized that the
Metalloid Carbide These are composed of carbon and the metalloids like germanium, astatine, arsenic, carbon, etc. Example of this egory is Carbon Derived Carbon(CDC). These have numerous appliions including their use as electrodes in electrical double layer capacitors, in chromatography, water desalination, filteration,etc.
Antimony is a metalloid (or semi metal), which is rather metal than nonmetal. Here its stable metallic modifiion is shown. In its nonmetallic form it is yellow, but unstable. Antimony is important for semiconductors, but has been used for a long time as additive in
Features of the Periodic Table Elements that have similar chemical properties are grouped in columns called groups (or families). As well as being nuered, some of these groups have names—for example, alkali metals (the first column of elements), alkaline earth metals (the second column of elements), halogens (the next-to-last column of elements), and noble gases (the last column of elements).
