Study Notes

Differences Between Organic and Inorganic Chemistry

  • Organic chemistry studies substances containing carbon, essential for all living organisms.
  • Organic compounds include gasoline, synthetic fabrics, plastics, and pesticides, originating from fossilized plants and animals.
  • Most organic substances are flammable due to their chemical structure.
  • Inorganic chemistry focuses on substances that do not contain carbon but may include hydrogen.
  • Inorganic compounds encompass metals, minerals, water, air, and ammonia and are not derived from living organisms.
  • Inorganic substances are non-flammable and do not exhibit the same biological processes as organic compounds.

Definition of Matter

  • Matter is anything that occupies space and has mass.
  • Exists in three states: solid, liquid, or gas.
  • Physical properties of matter include qualities that can be perceived through the senses, such as touch, taste, smell, and sight.
  • Energy, such as light and electricity, is not classified as matter since it does not possess mass, though it can affect matter.
  • The chemical properties of matter can only be observed during chemical changes or reactions.

Elements

  • An element is the most basic form of chemical matter, consisting of only one type of atom.
  • It cannot be chemically broken down into simpler substances without losing its identity.
  • There are currently 118 known elements, of which 98 occur naturally on Earth.
  • Synthetic elements are artificially created through chemical processes or synthesis.

Periodic Table Information for Carbon

  • Atomic Number: 6
  • Symbol: C
  • Element Name: Carbon
