    • is the physical science that deals with the composition, structure, and properties of substances and also the transformations that these substances undergo.
    •  is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and compounds

    Physical Chemistry
    • Mostly concerned with the study of chemicals containing the element carbon
    • the study of the structure, properties, composition, reactions, and preparation of carbon-containing compounds?
    Organic chemistry
    • the study of all elements of compounds other than organic compounds
    • the study of the synthesis, reactions, structures, and properties of compounds of the elements
    Inorganic Chemistry
    • The study of qualitative and quantitative analysis of elements and compounds
    • the science of obtaining, processing, and communicating information about the composition and structure of matter
    Analytical Chemistry
    • The study of reaction rates, mechanisms, bonding and structure
    • deals with the principles of physics involved in chemical interactions
    • in terms of the principles, practices, and concepts of physics such as motion, energy, force, time
    Physical Chemistry
  • Is the positively charged particle
    Proton
  • Negatively charged particle
    Electron
  • No change ( neutral particle )
    Neutron
  • Refers to the sum of the number of protons and neutrons
    Atomic Mass
  • A pure substance that cannot be decomposed into simpler substances; made up of only one kind of atom
    Example: Gold, copper, iron, hydrogen, oxygen
    Element
  • the process by which heat or electricity is directly transmitted through a substance 
    Conduction
  • the process by which sound waves travel through a medium.
    Conduction
  • Heat transfer through solids
    Conduction
  • Heat transfers through liquid or moist air
    Convection
  • the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. 
    Convection
  • Heat transfers through dry air or a vacuum / empty space
    Radiation
  • is energy that comes from a source and travels through space at the speed of light. 
    Radiation
  • Shortest wavelengths but highest energies
    Gamma rays
    X-rays
    UV rays
  • Longest wavelength but lowest energy
    Infrared
    Microwaves
    Radiowaves
  • Visible lights starting from the lowest energy (ROYGBIV)

  • A reaction that release energy is
    Exothermic
  • Chemical reactions that absorb (or use) energy are called 
    Endothermic
