Chemistry is the science

of the fundamental particles of matter.

And there is no way to escape

CHEMISTRY IS EVERYWHERE…

Chemistry is the science of matter, especially its chemical

reactions, but also its composition, structure and

properties. Chemistry is concerned with atoms and their interactions with other atoms,

and particularly with the properties of chemical bonds.

Chemistry is also concerned with the interactions between atoms (or groups of atoms) and various

forms of energy (e.g. photochemical reactions,

changes in phases of matter, separation of mixtures,

properties of polymers, etc.).

Chemistry is sometimes called "the central science" because it connects physics with other natural sciences such as geology and Biology. Chemistry

is a branch of physical science but distinct from physics.

HISTORY: In retrospect, the definition of chemistry has changed over time, as new discoveries and theories add to the functionality of the science. Shown below are some of the standard definitions used by various noted chemists:Alchemy (330) – the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies Chymistry (1661) – the subject of the material principles of mixed bodies Chymistry (1663) – a scientific art, by which one learns to dissolve bodies, and draw from them the different substances on their composition, and how to unite them again, and exalt them to a higher perfection Chemistry (1730) – the art of resolving mixed, compound, or aggregate bodies into their principles; and of composing such bodies from those principles Chemistry (1837) – the science concerned with the laws and effects of molecular forces Chemistry (1947) – the science of substances: their structure, their properties, and the reactions that change them into other substancesChemistry (1998) – the study of matter and the changes it undergoes.
