Chemistry - Wikipedia, the free encyclopedia - 0 views

  • Chemistry
  • Chemistry, a branch of physical science, is the study of the composition, structure, properties and change of matter.
  • Chemistry is chiefly concerned with atoms and their interactions with other atoms - for example, the properties of the chemical bonds formed between atoms to create chemical compounds.

  • Chemistry is sometimes called "the central science" because it bridges other natural sciences like physics, geology and biology with each other.
  • Chemistry is a branch of physical science but distinct from physics.
  • Etymology
  • The word chemistry comes from the word alchemy, an earlier set of practices that encompassed elements of chemistry, metallurgy, philosophy, astrology, astronomy, mysticism and medicine; it is commonly thought of as the quest to turn lead or another common starting material into gold.
  • Alchemy, which was practiced around 330, is the study of the composition of waters, movement, growth, embodying, disembodying, drawing the spirits from bodies and bonding the spirits within bodies
  • An alchemist was called a 'chemist' in popular speech, and later the suffix "-ry" was added to this to describe the art of the chemist as "chemistry".
  • The word alchemy in turn is derived from the Arabic word al-kīmīā (الکیمیاء). In origin, the term is borrowed from the Greek χημία or χημεία.
  • This may have Egyptian origins.
  • Many believe that al-kīmīā is derived from the Greek χημία, which is in turn derived from the word Chemi or Kimi, which is the ancient name of Egypt in Egyptian.
