About two thirds of the human body, and nine tenths of water, is oxygen. The gas is colourless, odourless, and tasteless. Liquid and solid oxygen are pale blue (see picture above) and strongly paramagnetic (contains unpaired electrons). Ozone (O 3) is the second allotrope of oxygen.
Oxygen is a chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and a potent oxidizing agent that readily forms oxides with most elements as well as with other compounds.
1st shell can hold 2 electrons. 2nd shell can hold 8 electrons. 3rd shell can hold 18 electrons. 4th shell can hold 32 electrons. Now the atomic number of oxygen (O) is 8. Hence the oxygen element has electrons arrangement 2, 6. This electron arrangement indicates that the outermost orbit of Oxygen element (O) has 6 electrons.
Oxygen is the eighth element of the periodic table. These oxygen facts contain chemical and physical data along with general information and history.
Electron Configuration Notation: -shows the arrangment of electrons around the nucleus of an atom. - helps chemist understanding how elements form chemical bonds. - can be written using the period table or an electron configuration chart. How to Write the Electron Configuration for Oxygen. Oxygen is the eighth element with a total of 8 electrons.
oxygen (O), nonmetallic chemical element of Group 16 (VIa, or the oxygen group) of the periodic table. Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a
Oxygen is an element number 8 from non-metals family. Its symbol is O. Oxygen atomic weight is 15.99943 amu. O stable and long lived isotopes are 16 O: 99.762%, 17 O: 0.038%, 18 O: 0.200%. Oxygen electronic configuration is 1s 2 2s 2 2p 4.
