Formal charges in ozone and the nitrate anion. In chemistry, a formal charge (F.C. or q*), in the covalent view of chemical bonding, is the hypothetical charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
As an example, summing bond orders in the ammonium cation yields −4 at the nitrogen of formal charge +1, with the two numbers adding to the oxidation state of −3: The sum of oxidation states in the ion equals its charge (as it equals zero for a neutral molecule). Also in anions, the formal (ionic) charges have to be considered when nonzero.
Even though nitrogen in NCl 3 is bearing a negative charge, the compound is usually called nitrogen trichloride. Chlorination of metals with Cl 2 usually leads to a higher oxidation state than bromination with Br 2 when multiple oxidation states are available, such as in MoCl 5 and MoBr 3. Chlorides can be made by reaction of an element or its ...
Dichlorine hexoxide is the chemical compound with the molecular formula Cl 2 O 6, which is correct for its gaseous state.However, in liquid or solid form, this chlorine oxide ionizes into the dark red ionic compound chloryl perchlorate [ClO
Dichlorine monoxide (IUPAC name: oxygen dichloride) is an inorganic compound with the molecular formula Cl 2 O. It was first synthesised in 1834 by Antoine Jérôme Balard, [2] who along with Gay-Lussac also determined its composition.
CL2 may refer to: Chlorine gas, Cl 2; the Clausen function of order 2, Cl 2; the Clifford algebra on , CAS latency 2, a rating ...
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not 1 / 2 e, or −3.8 e, etc. (There may be exceptions to this statement, depending on how "object" is defined; see below.)
The bromide ion acquires a positive formal charge. At this moment the halogen ion is called a "bromonium ion" or "chloronium ion", respectively. When the first bromine atom attacks the carbon–carbon π-bond, it leaves behind one of its electrons with the other bromine that it was bonded to in Br 2.
