characteristics of oxygen

Liquid oxygen is slightly paramagnetic. The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for the paramagnetism of oxygen. The periodic table is made up of 118 elements. Then put a pipe with hy­dro­gen un­der the cylin­der. Hydrogen molecules violently react with oxygen when the existing molecular bonds break and new bonds are formed between oxygen and hydrogen atoms. content of arterial blood, may be harmful. Physical Properties of Oxygen. It’s of great interest because it’s the essential element in the respiratory processes of most of the living cells and in combustion processes. Physical Properties Oxygen exists in all three forms - liquid, solid, and gas. Don’t try to re­peat these ex­per­i­ments with­out a pro­fes­sion­al su­per­vi­sion! 3. For this ex­per­i­ment, fill a glass crys­tal­liz­er with a vol­ume of 3 liters two thirds full of wa­ter and add a ta­ble­spoon of sodi­um hy­drox­ide or potas­si­um hy­drox­ide. The large values of the electronegativity and the electron affinity of oxygen are typical of elements that show only nonmetallic behaviour. Oxygen is a highly reactive element, highly paramagnetic, and is easily capable of combining with other elements. By entering your email address you agree to our Privacy Policy. Electrolysis of water containing small proportions of salts or acids to allow conduction of the electric current: When required in tonnage quantities, oxygen is prepared by the fractional distillation of liquid air. Oxygen, in both of its liquid and solid state, appear as clear, sky-blue color compound. Check your recollection of the characteristics of oxygen with an interactive quiz and printable worksheet. In all of its compounds, oxygen assumes a negative oxidation state as is expected from the two half-filled outer orbitals. Ozone may be produced from oxygen according to the equation: The process, as written, is endothermic (energy must be provided to make it proceed); conversion of ozone back into diatomic oxygen is promoted by the presence of transition metals or their oxides. After hydrogen and helium, It is the third-most abundant element in the universe by mass. Ac­cord­ing­ly, the more en­er­get­ic com­bus­tion of oxy­gen in the at­mos­phere is ex­plained by the swifter sup­ply of oxy­gen to the place of com­bus­tion. Characteristics and Properties Under standard conditions oxygen forms a gas that is composed of molecules consisting of two oxygen atoms (O 2). It forms a large range of covalently bonded compounds, among which are oxides of nonmetals, such as water (H2O), sulfur dioxide (SO2), and carbon dioxide (CO2); organic compounds such as alcohols, aldehydes, and carboxylic acids; common acids such as sulfuric (H2SO4), carbonic (H2CO3), and nitric (HNO3); and corresponding salts, such as sodium sulfate (Na2SO4), sodium carbonate (Na2CO3), and sodium nitrate (NaNO3). What aris­es as a re­sult of the com­bus­tion of hy­dro­gen, and what ox­ide is formed? The paramagnetic behaviour of oxygen confirms the presence of such electrons. What is an Oxygen Sensor? Hy­dro­gen ox­i­dizes to wa­ter. The physical and chemical properties of oxygen are: Oxygen is available in all three forms, solid, gas and liquid. The el­e­ment is also present in min­er­als in the form of salts and ox­ides. In the molecular diatomic form there are two unpaired electrons that lie in antibonding orbitals. Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent). The elemental structure is actually a cubic cr… The liquid and solid forms are a pale blue color and are strongly paramagnetic. As described in the section on allotropy, oxygen forms the diatomic species, O2, under normal conditions and, as well, the triatomic species ozone, O3. 2. The liquid and solid forms are a pale blue color and are strongly paramagnetic. Oxygen is essential to human life, it is found in … Please choose a different one. Oxygen is a highly reactive element. Major steps in the operation include the following: (1) Air is filtered to remove particulates; (2) moisture and carbon dioxide are removed by absorption in alkali; (3) the air is compressed and the heat of compression removed by ordinary cooling procedures; (4) the compressed and cooled air is passed into coils contained in a chamber; (5) a portion of the compressed air (at about 200 atmospheres pressure) is allowed to expand in the chamber, cooling the coils; (6) the expanded gas is returned to the compressor with multiple subsequent expansion and compression steps resulting finally in liquefaction of the compressed air at a temperature of −196 °C; (7) the liquid air is allowed to warm to distill first the light rare gases, then the nitrogen, leaving liquid oxygen.
