Transcript of "Section 3 - Chemistry"

  1. 1. The Chemistry of Life Biology I Factoids
  2. 2. Factoid #1 <ul><li>All living things must be able to adapt, get and use energy, respond to stimulus, reproduce, have DNA, grow and develop, and be made up of cells. </li></ul>
  3. 3. Factoid #2 <ul><li>Atoms are made up of protons, neutrons, and electrons. </li></ul>
  4. 4. Factoid #3 <ul><li>Protons and Neutrons are found in the nucleus and electrons are found orbiting the nucleus. </li></ul>
  5. 5. Factoid #4 <ul><li>Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. </li></ul>
  6. 6. Factoid #5 <ul><li>The periodic table is a list of known elements that include the metals, non-metals, and metaloids. </li></ul>
  7. 7. Factoid #6 <ul><li>The atomic number, that is found on the periodic table, is the number of protons in the that atom. </li></ul>
  8. 8. Factoid #7 <ul><li>In a neutral atom the number of protons equal the number of electrons. </li></ul>
  9. 9. Factoid #8 <ul><li>Two electrons will fit in the first energy level and eight electrons will fit in the 2 nd and 3 rd levels. </li></ul>
  10. 10. Factoid #9 <ul><li>Atoms form bonds in order to have full, stable outer energy level. </li></ul>
  11. 11. Factoid #10 <ul><li>The three types of bonds are hydrogen, ionic, and covalent bonds. </li></ul>
  12. 12. Factoid #11 <ul><li>Hydrogen bonds are very weak bonds between hydrogen atoms. </li></ul>
  13. 13. Factoid #12 <ul><li>When electrons are gained, lost, or transferred, the atom becomes either a positive or negative ion and an ionic bond forms. </li></ul>
  14. 14. Factoid #13 <ul><li>When electrons are shared between atoms a covalent bond forms. </li></ul>
  15. 15. Factoid #14 <ul><li>Large molecules and atoms bonded to itself are covalent. </li></ul>
  16. 16. Factoid #15 <ul><li>The chemical formula for water is H 2 O. </li></ul>
  17. 17. Factoid #16 <ul><li>Water is the universal solvent, a temperature stabilizer, and can form ions. </li></ul>
  18. 18. Factoid #17 <ul><li>Adhesion is when water sticks to other surfaces and cohesion is when water sticks to other water molecules. </li></ul>
  19. 19. Factoid #18 <ul><li>Water forms a polar covalent bond with the hydrogen side slightly positive and the oxygen side slightly negative. </li></ul>
  20. 20. Factoid #19 <ul><li>Water will split into H+ and –OH. </li></ul>
  21. 21. Factoid #20 <ul><li>The pH scale goes from 0-14; </li></ul>0 14 7 A c i d s B a s e s
  22. 22. Factoid #21 <ul><li>The more H+ in a solution, the more acid a solution is. </li></ul>
  23. 23. Factoid #22 <ul><li>When the –OH is equal to the H+, the solution is neutral (pH 7). </li></ul>
  24. 24. Factoid #23 <ul><li>The lower the pH the stronger the acid and the higher the pH the stronger the base. </li></ul>
