How halogen bromine is used to protect the pool. Halogen bromide (atomic number: 35, atomic weight: 79.9) is the only nonmetallic element that is liquid at room temperature. Bromine, originally manufactured by Carl Lowig, has nothing to do with him, he believes he created elements of priority in his student life, Antoine-Jérôme Balard discusses his discovery in 1826.
Bromine is a multifunctional compound which is mainly used for the production of flame-retardant materials, especially for children. (See Figure 2). In order to process the swimming pool and hot tub water, bromine has higher potency, so we begin to replace chlorine as a disinfectant. Upon incorporation into the compound, the bromine atom plays an important role in the treatment of pain, cancer and Alzheimer's disease. Helium is one of many non-metallic gases. Other non-metallic gases include hydrogen, fluorine, chlorine, and all 18 precious metal (or inert) gases. Since helium is chemically non-reactive, it is suitable for non-flammable applications such as balloons (see Figure 3) and lasers. Liquid helium exists at very low temperatures and can be used to cool superconducting magnets for imaging studies (MRI, MRI)
Bismuth is an active metal. Combining with oxygen, halogen, and other non-metals is easy. Halogen is Group 17 (VIIA) of the periodic table of elements including fluorine, chlorine, bromine, iodine and ast. It also reacts with water and most acids. To prevent cockroaches from having seven natural isotopes, it is highly reactive and must be stored in kerosene, petroleum or other oily liquids: -137 and -138. An isotope is an element in two or more forms. The isotopes differ from one another according to their mass number. The number written to the right of the element name is the mass number. Mass number represents the number of protons and neutrons in the element's nucleus. Elements are determined by the number of protons, but the number of neutrons contained in one element varies. Each variant is isotope
