  1. ATOMS And the Periodic Table

  2. Atom Smallest part of any element that contains all properties of that element.

  3. Subatomic Particles Review Particles that are smaller than an atom.

  4. 3 main subatomic particles are the proton, neutron and electron.

  5. Nucleus The center of an atom. It contains two particles: neutron and proton. Has a positive charge.

  6. ______

  7. Proton Positively charged particle found in the nucleus.

  8. Proton

  9. Neutron Particle in the nucleus of an atom that does not have a charge. It is a neutral particle.

  10. Neutron

  11. Electron Particle orbiting the nucleus of an atom. It has a negative charge.

  12. Electron

  13. Number of Protons Equals Number of electrons This is what gives the atom a neutral charge.

  14. The Big Picture!

  15. Neutron Proton Electron

  16. Is a chart that contains all the information of the 109 elements found on Earth.

  17. Are the simplest type of pure substances. They occur naturally within the Earth.

  18. Reading the Periodic Table

  19. Explains how to read the information that is given in each square of the periodic table.

  20. Atomic Number 6 C Symbol Element Name Carbon Atomic Mass 12.011

  21. represents the number of protons found in the atom’s nucleus.

  22. 6 C Carbon 12.011 Atomic Number

  23. None of the elements have the same number of protons.

  24. You can determine the element by knowing the atomic number.

  25. Atomic Number Practice

  26. Which element has the atomic number 26?

  27. Consists of one or two letters that represents that element.

  28. 6 C Carbon 12.011 Symbol

  29. First letter is always capitalized. Fe H

  30. If there is a second letter, it is written in lower case. Fe

  31. Symbol Practice

  32. How would you write the symbol for Neon?

  33. The Name of the Element is always spelled out.

  34. 6 C Carbon 12.011 Element Name

  35. Element Name Practice

  36. What is the name of the element that has the symbol Fe? Iron

  37. The sum of the number of protons and number of neutrons found in the nucleus of the atom for that element.

  38. Protons + Neutrons Atomic Mass =

  39. 6 C Carbon 12.011 Atomic Mass

  40. Atomic Mass Practice

  41. What is the atomic mass if an atom has 2 protons and 2 neutrons?

  42. How many protons does an atom have if its atomic mass is 12 and it has 6 neutrons?

  43. Which element has an atomic mass of 12 and contains 6 neutrons?

  44. How many neutrons does an atom contain if its atomic mass is 65 and it contains 30 protons?

  45. Which element has an atomic mass of 65 and contains 30 protons?

  46. Valence Electron Electrons in the OUTERMOST energy level of an atom.

  47. Valence Electron

  48. Valence Electron Determines how atoms will combine. Groups on the periodic table can be arranged by Valence Electrons
