Fancy Bonding Sometimes, atoms share more than one electron. Occasionally, they can share 2 or even 3 electrons. These are called double and triple bonds. Chemical Formulas Molecules are represented by a chemical formula. The chemical formula tells you the exact number of each kind of atom in ...

In benzene, the prototypical aromatic compound, 18 bonding electrons bind 6 carbon atoms together to form a planar ring structure. The bond "order" (average number of bonds) between the different carbon atoms may be said to be (18/6)/2=1.5, but in this case the bonds are all identical...
Chemical formula, any of several kinds of expressions of the composition or structure of chemical compounds. The forms commonly encountered are empirical, molecular, structural, and projection formulas. An empirical formula consists of symbols representi
Bonding involves only valence electrons Remember… The noble gases are particularly stable because their outer shell is full of electrons (usually 8) Octet Rule: Atoms tend to gain, lose, or share electrons until they are surrounded by eight valence electrons (noble gas configuration) ...

*Theme/Title: Ionic Bonding II: Nomenclature * Description/Instructions One of the most important requirements of chemistry is communication of information to others. Chemists discuss compounds by using both formulas and names. Names of compounds are universal. Therefore, a set of rules is used in...
The importance of bonding connectivity is nicely illustrated by the structures of the two compoundsethanolanddimethyl ether, both of which have thesimplest formulaC2H6O. Thestructural formulasreveal the very different connectivities of these two molecules whose physical and chemical properties are quite di...
However, these reactions often require activation energy (discussed in more detail in the module Chemical Bonding: The Nature of the Chemical Bond), which can be provided by a ‘spark’ or source of energy for ignition. Fuel, oxygen, and energy are the three things make up what is known ...
(Tin and lead can also form molecular compounds in which all four valence electrons are involved in covalent bonding.) Elements from the d-block form 2+, 3+, or, in a few cases, 1+ or 4+ cations. Many d-block elements form two ions of different charges. For example, copper form...
