Several of the CPK colors refer mnemonically to colors of the pure elements or notable compound. For example, hydrogen is a colorless gas, carbon as charcoal, graphite or coke is black, sulfur powder is yellow, chlorine is a greenish gas, bromine is a dark red liquid, iodine in ether is violet, amorphous phosphorus is red, rust is dark orange-red, etc.
Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
NanoProfessionals have alternate molecular structures for the top of the head, and possibly include a hat. Most can be synthesized from the NanoKid by an acetal exchange reaction with the desired 1,2- or 1,3- diol, using p-toluenesulfonic acid as catalyst and heated by microwave irradiation for a few minutes. The ultimate set of products was a ...
Salter Science was a brand of science kits sold by Thomas Salter Ltd., a Scotland-based company which manufactured toys and science activity kits for children. [1] Kits included activities with electricity, microscopy, magnetism and crystal gardens, but the company is probably best known for their chemistry sets. The company also produced other ...
The activity is dedicated to synthesizing metal oxide semiconductor nanomaterials, forming nanostructures on metal oxides and extracting organic dyes from the plants of Nepal for applications including Optoelectronic devices like solar cells. The activities will be extended in the domain of metal nanoparticles as well as polymer materials.
Organic chemistry is the study of organic, or carbon based, molecules.Carbon is the only element that can make bonds with itself so that chains are produced, silicon has similar properties, but Carbon is a main element in everyday life, and thus, is lucky enough to have a whole subject in chemistry dedicated to it.
In chemistry, trigonal planar is a molecular geometry model with one atom at the center and three atoms at the corners of an equilateral triangle, called peripheral atoms, all in one plane. [1] In an ideal trigonal planar species, all three ligands are identical and all bond angles are 120°. Such species belong to the point group D 3h.
