Understanding Chemistry

Understanding ChemistryNomenclature Definition Chemistry is a branch of the science known as organic chemistry. This science is concerned with the chemical makeup of substances and their reactions in the body, and has been used since the early days of civilization.Nomenclature Definition atoms are the smallest particles that constitute a substance, and are comprised of protons and neutrons, and have no hole in their center minus energy. An atom has two faces and one end. There are six types of atoms: sulphur, sulphides, hydroxides, phosphates, nitrates, and carbides.Nomenclature Definition Alkali Metal - The word alkali is derived from the Greek alkali, which means acid. The alkali metal has the property of reacting with the air in water to form different kinds of acidic compounds. Acid can be obtained by the action of water on the alkali metal. It reacts with water molecules when they come into contact with the alkali metal.Nomenclature Definition Oxalate - The oxalate is the most c ommon compound produced by reaction of oxalic acid. The oxalate is a component of many fruits and vegetables. The oxalate is found in almost all organisms that live in the soil, as well as plants and animals.Nomenclature Definition Root Ferula - Root ferula is a kind of plant related to the cress, which is widely cultivated. It is a vine having underground stems that sprout leaves at the top. The roots grow upward from the top of the leaves and when these become developed, they are able to absorb some of the water.Nomenclature Definition Molecular Size - The molecular size is defined as the smallest spaceoccupied by an element when it is compressed. The molecule consists of smaller parts called subunits which make up the total size of the molecule. Each subunit is made up of molecules with different sizes.Nomenclature Definition Bromine - Bromine has a very important role in today's world. It is used as a white pigment for pigments, photographic films, sealants, paints, varnishes, s olvents, batteries, lubricants, coke, some drugs, and solvents. Bromine has been used as a chemical weapon since the early 1900s. This was during World War I.Nomenclature Definition - The definition and description of these elements as well as the properties of their compounds is maintained by the National Institute of Standards and Technology. In this way, chemistry is a discipline which continuously strives to improve the quality of the scientific and technological environment.
