Form 4 and Form 5 Chemistry Definition

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 (Zosimos).[28]
  • Chymistry (1661) – the subject of the material principles of mixed bodies (Boyle).[29]
  • 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 (Glaser).[30]
  • Chemistry (1730) – the art of resolving mixt, compound, or aggregate bodies into their principles; and of composing such bodies from those principles (Stahl).[31]
  • Chemistry (1837) – the science concerned with the laws and effects of molecular forces (Dumas).[32]
  • Chemistry (1947) – the science of substances: their structure, their properties, and the reactions that change them into other substances (Pauling).[33]
  • Chemistry (1998) – the study of matter and the changes it undergoes (Chang).[34]

Basic Chemistry

The key to success is to know the basic chemistry building blocks of the pyramid.
States of matter and the particle theoryElements and the Periodic tableSeparating mixtures into pure substancesAtoms and moleculesCompoundsChemical formulaAcids and basesChemical reactionsChemical equationsMole chemsitryHome
The understanding of chemistry involves a progression in the sequences of certain chemical concepts.

The basic building blocks start with the junior high school years and develop into the senior years.

While high school chemistry students study a much larger range of topics the key to success is to be firmly established in the each of the above chemical building blocks.
