Sample Exercise 2.1 Illustrating the Size of an Atom
... Because the name pentane contains the prefix penta- for five (Table 2.6), we can assume that pentane contains five carbon atoms bonded in a chain. If we then add enough hydrogen atoms to make four bonds to each carbon atom, we obtain the following structural formula: ...

The detection of individual elements in a mixture with other accompanying elements is a rather difficult problem, because all of them can interact with the same reagents with a similar outward effect. Using specific reagents and reactions, makes it possible to detect some elements in mixtures with a ...

Inorganic chemistry

Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, and there is much overlap, most importantly in the sub-discipline of organometallic chemistry. It has applications in every aspect of the chemical industry–including catalysis, materials science, pigments, surfactants, coatings, medicine, fuel, and agriculture.
