Elements and periodic table

  1. 1. Elements and the Periodic Table
  2. 2. Matter: <ul><li>Anything that has mass and takes up space. </li></ul>
  3. 3. = Matter
  4. 4. = Matter
  5. 5. States of Matter -Solid -Liquid -Gas
  6. 6. Solid: <ul><li>Definite shape </li></ul><ul><li>Definite volume </li></ul>
  7. 7. Gas: <ul><li>No definite shape </li></ul><ul><li>No definite volume </li></ul>
  8. 8. Liquid: <ul><li>No definite shape </li></ul><ul><li>Definite volume </li></ul>
  9. 9. Elements
  10. 10. Elements: <ul><li>Simplest pure substances </li></ul><ul><li>Elements are made up of atoms </li></ul>Examples: <ul><li>Hydrogen </li></ul><ul><li>Oxygen </li></ul><ul><li>Calcium </li></ul>
  11. 11. Compounds
  12. 12. Compound: <ul><li>Pure substances made up of more than one element. </li></ul><ul><li>Atoms of the elements in a compound are chemically </li></ul><ul><li>bonded together to form molecules. </li></ul><ul><li>Molecules are changed during chemical reactions. </li></ul>
  13. 13. Mixtures
  14. 14. Mixtures: <ul><li>Consists of two or more substances mixed together but not </li></ul><ul><li>chemically combined. </li></ul><ul><li>Substances in mixtures can be separated by physical means. </li></ul><ul><li>Types of mixtures: </li></ul><ul><li>Heterogeneous: not identical throughout </li></ul><ul><li>Homogeneous: identical properties throughout </li></ul>
  15. 15. Heterogeous:
  16. 16. Homogeneous:
  17. 17. Periodic table
  18. 18. Periodic table
  19. 19. <ul><li>Dmitri Medeleev- father of the periodic table of elements. </li></ul><ul><li>Groups- are families of elements with similar physical or chemical </li></ul><ul><li>properties that occupy the same column. There are 18 groups within the </li></ul><ul><li>periodic table. </li></ul><ul><li>Periods- are horizontal rows of elements whose properties change </li></ul><ul><li>gradually are predictably. There are 7 periods within the periodic table. </li></ul><ul><li>An element is identified by its chemical symbol. </li></ul><ul><li>The number above the symbol is the atomic number. </li></ul><ul><li>The number below the symbol is the rounded atomic weight of the </li></ul><ul><li>element. </li></ul>
  20. 20. Information within the periodic table <ul><li>Properties of elements </li></ul><ul><li>Metals- elements that is a good conductor of electricity </li></ul><ul><li>and heat, usually is shinny, deductive, and malleable. </li></ul><ul><li>Metalloids- elements that shares properties with metals and </li></ul><ul><li>nonmetals. </li></ul><ul><li>Nonmetals- elements that are poor conductors of heat and electricity. </li></ul><ul><li>they can be a gas or a brittle solid at room temperature. </li></ul><ul><li>Atomic number = Protons Electrons </li></ul><ul><li>neutrons = rounded </li></ul><ul><li>Atomic mass – atomic number </li></ul>
