Zinc oxide, ZnO, was a useful white paint pigment; however, pollutants tend to discolor the compound. The compound is also important in the manufacture of automobile tires and other rubber goods, and in the preparation of medicinal ointments. For example, zinc-oxide-based sunscreen...
oxidation states−1, −2, +2 (in compounds with fluorine) electron config.1s22s22p4 History Oxygen was discovered about 1772 by a Swedish chemist,Carl Wilhelm Scheele, who obtained it by heatingpotassium nitrate, mercuricoxide, and many other substances. An English chemist,Joseph Priestley, ...
It is capable of combining with all elements, with the exception of fluorine, to form oxides, bases, oxyacid anhydrides, etc. At room temperature, oxygen is only moderately active with most substances. However, at higher temperatures, it becomes very active that it is considered as one of ...
The more subatomic materials in an atom the heavier and more dense it will be. Uranium has a mass number of 235. The number of electrons in the outer orbits determines the chemical properties of an element. All the members of the group of elements known as the halogens (fluorine, ...
The density of negatively charged fluorine atoms is more than an order of magnitude larger than the electron density, and the density of CF3− ions is comparable. The results presented in Fig. 39 were obtained by a particle-in-cell simulation code for the case where plasma is sustained by...
and the majority of these have half-lives that are less than 83 milliseconds.[57] The most common decay mode of the isotopes lighter than 16O is β+ decay[61][62][63] to yield nitrogen, and the most common mode for the isotopes heavier than 18O is beta decay to yield fluorine.[57...

Only fluorine has higher electronegativity and is thus a stronger oxidizer.Besides the essential use to support life, oxygen has many other uses.It is used in the smelting process to free metals from their ores. It is particularly importantin the oxygen-converter process in the production of ...
Oxygen has, except for fluorine, the highest electronegativity and electron affinity of any element; the values of these properties then decrease sharply for the remaining members of the group to the extent that tellurium and polonium are regarded as predominantly metallic in nature, tending to lose...
