  1. Chapter Six: The Atom • 6.1 Fundamental Particles and Forces • 6.2 Electrons in the Atom

  2. What is matter made from? ATOMS!

  3. Water is matter made from 3 atoms. 2 Hydrogen atoms and 1 Oxygen atom H2O H2O

  4. What is an atom?

  5. What is an atom? • Atoms are the smallest form of matter. • Each element has a different kind of atom

  6. What are atoms made of? • Protons (+) • Neutrons (0) • Electrons (-)

  7. What is in the center of an atom? Protons and Neutrons in the nucleus

  8. What is surrounding the nucleus? Electrons

  9. Which part has the least mass? • Electrons • Protons and Neutrons are big in comparison Neutron

  10. What keeps the electrons from flying off? • Electrons are bound to the nucleus by the attractive force between electrons (-) and protons (+).

  11. List the charges Protons-- positive (+) Electrons--negative (-) Neutrons--no charge (0) (neutral)

  12. Question 1 What part of the atom has no charge and is found in the nucleus? NEUTRON

  13. Question 2 The number of protons and electrons in an atom are the same. (T/F) TRUE

  14. Question 3 Neutrons are about the same size as _________. PROTONS

  15. Question 4 An atom could be described as: Electrons in the center with protons in random patterns around them. (T/F) FALSE

  16. Question 5 If an atom has 7 protons how many electrons will it have? 7

  17. Atoms, Elements and the Periodic Table

  18. Each element on the Periodic Table has it’s own unique atom Atom #2 Atom #20

  19. How are atoms of different elements different? The atoms of different elements contain different numbers of protons in the nucleus. helium=2 protons calcium=20 protons

  20. What is the atomic number? Because the number of protons is so important, it is called the atomic number.

  21. How many protons does Oxygen have? Protons Atomic mass EIGHT

  22. Question 6 The atomic number is the number of ___________. PROTONS

  23. Question 7 All gold atoms have the same number of ______________. PROTONS

  24. Question 8 What is the atomic number of potassium?

  25. Question 9 In a Silver atom with a mass number of 108 and an atomic number of 47, what is the number of protons? 47

  26. Question 10 How many electrons does an atom of Nitrogen have?

  27. The Atom Board The Atom • What is inside an atom?

  28. Make an atom with 5 protons

  29. Make Lithium (Li)

  30. Make Beryllium (Be)

  31. Make a Helium (He) atom with a mass of 4.

  32. Make a atom with 6 electrons.
