chemical Reactions DM

  1. 1. Elements, Atoms, Compounds and Molecules. <br />By D’Arcy Meredith<br />
  2. 2. Elements<br />An element is a pure substance made up of one type of atom. <br />
  3. 3. Atoms<br />An atom a fundamental piece of matter made up of protons, neutrons and electrons.<br />Electrons<br />Protons<br />Neutrons<br />
  4. 4. Metals<br />Metal is an element, compound, or alloy characterized by electrical and heat conductivity . <br />
  5. 5. What is non-metal?<br />A non-metal is an element on the periodic table that does not have the properties of a metal element such as malleability. Non metals are usually found as gases in nature or weak, brittle solids. <br />
  6. 6. Periodic Table<br />Description of what a periodic table is?<br />
  7. 7. What is a compound?<br />A chemical compound is a substance composed of two or more different elements chemically bonded together in a fixed proportion by mass.<br />
  8. 8. Chemicsal Reaction<br />A chemical reaction is a process that leads to the transformation of one set of chemicals substances to another.<br />
  9. 9. Identify a chemical reatcion<br />Production of heat, light, gas or precipitate.<br />
  10. 10. Physical and Chemical changes.<br />A chemical change is non reversible as a physical change is. For example, the burning of wood is a chemical change, as you can&apos;t unburn it, whereas the freezing of water would be a physical change because it can be reversed. <br />
  11. 11. Factors affecting a Reaction Rate.<br />Temperature, concentration, size of particles or using a catalyst. <br />Add a picture.<br />
  12. 12. Bibliography<br /><br /><br /><br /><br /><br /><br /><br /><br />
