  4. Page 39 10 boxes down, horizontal line Everything I Know About Chemistry:

  5. Page 39 10 more boxes down, horizontal line Everything I Want to Know About Chemistry:

  6. Page 39 Remaining space The Beginnings of Chemistry:

  7. The Beginnings of Chemistry Democritus develops the idea of the atom around 400 BCE 460 BC He pounded up materials in his pestle and mortar until he had reduced them to smaller and smaller particles which he called ATOMA greek for not to be divided (cut)

  8. The Beginnings of Chemistry Another Greek philosopher, Heraclitus, suggested everything was made out of fire 460 BC The world itself consists of a law-like interchange of elements, symbolized by fire. Thus the world is not to be identified with any particular substance, but rather with an ongoing process governed by a law of change.

  9. The Beginnings of Chemistry Aristotle announced that there were four elements, or basic substances, from which all else was composed 460 BC Air, Earth, Fire, and Water; He believed that everything else, was a blend of these four.

  10. Homework Read and fully annotate “Matter, Elements, and Atoms” reading on page 40 Add the 5 underlined words and their definitions to your Vocabulary section

  11. Exit Ticket Why should the slope of your line of best fit in the Circumference vs Diameter Lab have been close to 3.14?

  12. Take Out Pencil Catalyst Sheet Science Notebook, Open to Vocabulary section

  13. Catalyst Describe the difference between matter and mass Describe the difference between an atom and an element

  17. Chemistry Chemistry is the study of the composition, properties, and behavior of MATTER

  18. The Beginnings of Chemistry Democritus develops the idea of the atom around 400 BCE 460 BC He pounded up materials in his pestle and mortar until he had reduced them to smaller and smaller particles which he called ATOMA greek for not to be divided (cut)

  19. Aluminum

  20. An Aluminum Atom

  21. How small is an atom? It would take 40,000,000 aluminum atoms to make a 1 cm line of aluminum

  22. ElementAtom What is an element? What is an atom?

  23. ElementAtom An atom is the smallest particle of an element that still has all the properties of an element. An element is a pure substance that cannot be broken down into any other substances.

  24. An atom is composed of three main subatomic particles Atom Subatomic Particles

  25. Subatomic particles are…. The smaller parts that make up an atom

  26. An atom is composed of three main subatomic particles Atom Protons Neutrons Electrons

  27. Protons, Neutrons and Electrons are the building blocks of atoms

  28. Nucleus The nucleus is the center of the atom, where the protons and neutrons are located.

  29. A proton has one positive charge and a mass equal to one mass unit. A neutron has no charge and a mass that is also equal to one mass unit. Neutron Neutral Charge Proton + Charge What charge does the nucleus have as a whole?

  30. 6 C Carbon 12.011 The name of the element

  31. 6 C Carbon 12.011 The element’s atomic symbol The name of the element

  32. 6 C Carbon 12.011 The atomic number of the element: This number tells you the number of protons in the atom. The element’s atomic symbol The name of the element

  33. 6 C Carbon 12.011 The atomic number of the element: This number tells you the number of protons in the atom. The element’s atomic symbol The name of the element The mass number or atomic mass: This number tells the mass of one atom. …which is approximately the sum of protons and neutrons in the nucleus, since each proton and each neutron has a mass equal to one mass unit.

  34. Using the beads on your table, create the nucleus of 1 Carbon atom Draw that nucleus in your notes 6 C Carbon 12.011

  35. Take Out Pencil Catalyst Sheet Science Notebook

  36. Catalyst Determine the number of protons and neutrons in the nucleus of one atom of each element listed below: 1. Helium 4. Bromine 2. Chlorine 5. Rubidium 3. Calcium 6. Xenon

  37. Remember: atomic mass - atomic number number of neutrons

  38. Atomic (Average) mass unit 6 C Carbon 12.011 Number of neutrons must be changing because we know that protons don’t Isotopes – Atoms of the same element that have a different number of neutrons from the average

  39. Electrons Electrons are located around the nucleus. They are so tiny that they almost have no mass. Each electron has a charge of negative 1 (-1). Electron Negative Charge

  40. In a neutral atom, how does the number of protons compare to the number of electrons? A neutral atom has an equal number of protons and electrons

  41. So, to review…

  42. 4 Be Beryllium 9.01

  43. The periodic table is an orderly listing of all the elements, arranged from left to right and top to bottom in order of increasing atomic number Review: what do the numbers mean?

  44. 6 C Carbon 12.011 The name of the element

  45. 6 C Carbon 12.011 The element’s atomic symbol The name of the element

  46. The atomic number of the element: This number tells you the number of protons in the atom. And because, in a neutral atom, the number of protons and the number of electrons are equal, it also tells the numberof electrons. 6 C Carbon 12.011 The element’s atomic symbol The name of the element

  47. Remember: Look at website! and this The atomic number of the element: This number tells you the number of protons in the atom. And because, in a neutral atom, the number of protons and the number of electrons are equal, it also tells the numberof electrons. 6 C Carbon 12.011 The element’s atomic symbol The name of the element The mass number or atomic mass: This number tells the mass of one atom, which is approximately the sum of protons and neutrons in the nucleus, since each proton and each neutron has a mass equal to one mass unit, and the electrons have virtually no mass. The color: Depending on the periodic table, will tell you what type of element it is. In Carbon’s case, it is a nonmetal

  48. 6 C Carbon 12.011 The number of protons. The number of electrons. The element’s atomic symbol The name of the element The number of protons + the number of neutrons
