• Inorganic chemistry


  Concerned with the properties and reactivity of all chemical elements
• Inorganic chemistry is not an isolated branch of chemistry, it deals with the chemistry of all non-organic compounds
• Advanced interests in inorganic chemistry

  • Role of metals in biology and the environment
  • Design and properties of materials for energy and information technology
  • Fundamental studies on the reactivity of main group and transition elements
  • Nanotechnology
• Matter


  The physical material of the universe that occupies space and has mass, composed of atoms and molecules
• Pure substance


  Matter that has fixed composition and distinct properties, homogeneous matter
• Pure substances


  • Water
  • Sodium chloride (table salt)
• Mixture


  Matter that consists of combinations of two or more substances, each substance retains its own chemical identity and properties
• Heterogeneous mixture


  Mixtures that do not have the same composition, properties, and appearance throughout, "Suspensions"
• Homogeneous mixture


  Mixtures where the composition and properties are uniform throughout, "Solutions"
• Element


  Cannot be separated into other substances by any ordinary chemical change, consist of just one kind of atom or "homoatomic molecules"
• Compound


  Can be decomposed into two or more simpler substances by any ordinary chemical change, "Heteroatomic molecules"
• Classification of elements


  • Metal
  • Non-metal
  • Metalloid
• Metal


  • Good conductor of heat and electricity, hard with high density and high melting points
• All metals are solid except mercury, which is the only liquid metal
• Non-metal


  • Poor conductor of heat and electricity, some are mostly gases except bromine which is a dark red liquid, solid non-metals like carbon, sulfur, phosphorus and iodine are brittle
• Metalloid


  Semi-metals or semi-conducting elements, have some properties or characteristics of both metals and non-metals
• Acid


  Chemical compounds that contain the hydrogen ion (H+), ionize in aqueous solutions to form hydrogen ions, turn blue litmus paper to red in aqueous solution
• Base


  Contain the hydroxide ions (OH-), dissociate in water to give hydroxide ions, turn red litmus paper to blue in aqueous solution
• Oxide


  Compounds formed from the reaction of oxygen with another element
• Types of oxides


  • Metallic oxides
  • Non-metallic oxides
• Salt


  Composed of a metal cation of an aqueous base and the anion from an aqueous acid
• Types of salts


  • Normal salts
  • Acidic salts
  • Basic salts
  • Mixed or complex salts
• Physical property


  Matter that can be observed or measured without changing the composition of the substance
• Types of physical properties

  • Extrinsic physical properties (mass, length, width, height, thickness, volume, temperature)
  • Intrinsic physical properties (boiling point, density, malleability, taste, refractive index)
• Chemical property


  Can be observed when matter undergoes a change, ability of a substance to undergo a change that alters its identity
• Examples of chemical properties


  • Flammability
  • Radioactivity
  • Explosiveness
  • Stability towards heat
  • Reaction to indicators
• Physical change


  Change in the form or state of matter but does not involve the properties and composition, change in the property of matter that does not result in a change of its basic identity
• Chemical change


  Substance is transformed into a chemically different form of substance, chemical reaction has taken place
• Indications of chemical change

  • Evolution of heat and light
  • Production of gas
  • Formation of precipitate
  • Disappearance of solid which cannot be attributed to more physical dissolution
  • Change in color
• Solid


  Matter that has a definite shape and volume
• Liquid


  Matter that has a definite volume but an indefinite shape, takes shape but retains volume
• Gas


  Matter that has neither a definite shape nor a definite volume
• Plasma


  Combination of a gas and a liquid or a gas alone at a very high temperature, "Boise condensate"
• Inorganic chemistry


  Concerned with the properties and reactivity of all chemical dienes, not an isolated branch of chemistry, deals with the chemistry of all non-organic compounds (without hydrogen bond)
• Inorganic chemistry


  • Advanced interests focus on understanding the role of metals in biology and the design and properties of materials for energy and information technology, fundamental studies on the reactivity of main group and transition elements, and ancischinokigy
• Matter


  The physical material of the universe, it occupies space and has mass, composed of atoms and molecules
• Pure substances


  Substances that have a fixed composition and distinct properties, homogeneous matter
• Mixture


  Matter that consists of combinations of two or more substances, each substance retains its own chemical identity and hence its own properties
• Heterogeneous mixture


  Do not have the same composition, properties, and appearance throughout, "Suspensions"
• Homogeneous mixture


  The composition and properties are uniform throughout, "Solutions"
