3 + 5 Cl − + 6 H + 3 Cl 2 + 3 H 2 O. Perchlorates and perchloric acid (HOClO 3) are the most stable oxo-compounds of chlorine, in keeping with the fact that chlorine compounds are most stable when the chlorine atom is in its lowest (−1) or highest (+7) possible oxidation states. Perchloric acid and aqueous perchlorates are vigorous and ...
Chlorine (17 Cl) has 25 isotopes, ranging from 28 Cl to 52 Cl, and two isomers, 34m Cl and 38m Cl. There are two stable isotopes, 35 Cl (75.8%) and 37 Cl (24.2%), giving chlorine a standard atomic weight of 35.45.
[3] Some chloroanions are stable in a solution in water, whereas others are decomposed. They may be stable in a molten salt, such as an ionic liquid. [4] In the solid form some are only stable with large cations, as when there are small cations they may form two separate chloride salt phases.
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
For mesons whose constituents are a heavy quark and its own antiquark the same notation applies as for atomic states. However, uppercase letters are used. However, uppercase letters are used. Furthermore, the first number is (as in nuclear physics) n = N + 1 {\displaystyle n=N+1} where N {\displaystyle N} is the number of nodes in the radial ...

A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that elements with similar behavior fall into ...
A more precise definition of triethylmethylammonium trichloride is given by the sum formula [NEt 3 Me][Cl(Cl 2) n] where n is the number of equivalents of dichlorine that are bonded. By addition of elemental chlorine to [NEt 3 Me]Cl ( n = 0), the value of n increases continuously forming the trichloride [NEt 3 Me][Cl 3 ] ( n = 1), the ...
