Glossary of chemistry terms

Template:Short description Template:TopicTOC-Chemistry This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter, as well as the changes it undergoes during chemical reactions; it features an extensive vocabulary and a significant amount of jargon.

Note: All periodic table references refer to the IUPAC Style of the Periodic Table.

A

Template:TermTemplate:Anchor Template:Ghat Template:Defn

The skeletal formula for a generic Template:Gli, where R denotes a variable carbon-containing substituent group

An Template:Gli with Template:Gli, Template:Gli, and Template:Gli labelled

Template:Term Template:Defn

C

The skeletal formula for a generic Template:Gli, with Template:Font denoting a variable carbon-containing substituent group

Template:Term Template:Ghat Template:Defn

Structural diagrams of two Template:Gli molecules, the non-superposable mirror-image enantiomers (S)-alanine (left) and (R)-alanine (right). Though they have identical Template:Gli and the same physical properties, they are nevertheless different chemicals, and react differently with other chiral compounds.

An example of large-scale, rapid Template:Gli

Template:Term Template:Defn

A diatomic hydrogen molecule, Template:Chem (right), is formed by a Template:Gli when two single hydrogen atoms share two electrons between them.

D

Template:Glossary Template:TermTemplate:Anchor Template:Ghat Template:Defn

A sodium ion (Na⁺) forms a solvation complex with water molecules when Template:Gli in an aqueous solution.

E

The skeletal formula for a generic Template:Gli, with R and R′ denoting variable carbon-containing substituent groups

The skeletal formula for a generic Template:Gli, with R and R′ denoting variable carbon-containing substituent groups

F

Template:Term Template:Defn

Template:Term Template:Defn

A diagram of a laboratory apparatus designed for Template:Gli

I

An Template:Gli between a sodium atom (Na) and a fluorine atom (F). The sodium atom loses its sole Template:Gli (leaving the atom with a positive Template:Gli), and the fluorine atom gains this same electron via an Template:Gli (giving the atom a negative electrical charge). The oppositely charged Template:Gli are then attracted to each other to form a new compound called sodium fluoride.

K

The skeletal formula for a generic Template:Gli, with R and R′ denoting variable carbon-containing substituent groups

M

Various ways of depicting a Template:Gli group in structural formulae

Template:Term Template:Defn

During Template:Gli, the transfer of solvent molecules out of the more dilute solution (in the left beaker, on the left side of the membrane) increases that solution's solute concentration, while the simultaneous addition of solvent to the more concentrated solution on the other side of the membrane decreases its own concentration. The eventual result is an equilibrium of the solute concentrations on both sides of the membrane, though the volumes on each side are no longer equal (right beaker).

The modern Template:Gli. The horizontal rows are called Template:Gli and the vertical columns are called Template:Gli or families.
